Enough with dyno numbers...i want to see some quarter mile times. I have a hard time believing that the predator will touch the SC down the strip; as the extra powerband on the SC should lay waste to the much more stock powerband of the predator.
And by the way for anyone who cares, I have found a nice trick for awesome off the line accel with the SC unit. Being that the SC is a little slow on the low end takeoff, i am putting my 4x4 to good use. From a dead stop, you can shift into 4wd (this is assuming you have shift on the fly), hold the brakes and rev the motor to about 2000 rpm (it stalls somewhere about 2100, 1900 is usually what i go to) and just let off the brake. It will sling your head back into the seat. After you get out of first and second gear, just drop the 4 wheel drive back to 2 wheel drive. And yes, it will shift under WOT. This technique works GREAT for launching.

Well, I decided to give the 1704 a try. I have run both the Edge w/ Attitude and the Predator back and forth now for over 3 months. I love the power of the edge, but hate the shifting. The predator shifts decently (but too harsh), the power isn't very smooth, and the coolant issue really bugs me.
I installed the 1704 Performance tune yesterday morning. So far, I am impressed with the power at WOT ONLY. The shifting is outstanding as well. The problem is that the truck feels virtually STOCK at all throttle levels below full. It's definitely not stock below full throttle, but no where near as responsive as the Predator and Edge. I will certainly miss this with the 1704 that the Edge and Predator had. SO, do I like it??? YES...but only from the standpoint of comparing it to the others at WOT. Compared to the others at partial throttle....I really DONT like it. I wish superchips could change the programming to give it the monster throttle response that the Edge has. Will I leave it on the truck??? Probably so. Once I get over the lack of throttle response, I'll probably love it. I wish there was a definite answer on stacking programmers and modules regarding the safety factor. If I could get the shifting of the 1704 combined with the throttle response of the Edge, we'd have the perfect combination.
--------------------------------------------------------------------------------
What are the hex calibrations codes in your truck? (for data log purposes)
These trucks have dead throttle response stock, and I did kick it up, but I didn't want to go crazy.
There is good reason for this (actually several really good reasons), but we are now skirting proprietary information.

Vic,
I agree with psdrob 100% here. I have the edge/attitude and just bought your sc 1704 also. What he is talking about is this, with the edge you barley have to hit the pedal and it is rippin. Also like pulling a hill or something like that the edge stays in overdrive and still pulls hard the sc feels like srock and must shift down. if you floor it the sc goes like hell. But it really lacks in low end power. you did a good job with the lagg. Its just the sc has ok take off resopse (though nothing like the edge!) thens kinda goes to a stock feeling then picks up again into a awsome high reving pull to almost 4k. You have done something here that no other programer has done. that is making the 6.0 pull hard clear to 4k. it is very impressive but why cant we get low end pull as well? if you could do that you would be selling these to everyone. I am the one thats been doing some testing that i know you do not recomend. i am looking for edge type power with the sc shifting. your shifts are awsome! I just did another test and now i know what you mean about how stock it wont even rev anywhere near where the sc does. I programed economy mode then back to stock but i unplugged it before it could tune the tranny back to stock. this woke me up on what you were saying. stock pulled to about 3500 rather weakly then finally got around 3800 and just quit pulling it finally shifted after about 5 seconds of barley pulling then pulled like crazy again after the shift. i even tried the edge/attitude same thing just quit pulling at about 3500 finally made it to 3900 and shifted but it did it no better than stock did. i think the sc 1704 makes alot of power its just not what we in the diesel world are used to. you created a high reving monster but unfortunatly most are used to the low reving freight train pull that other boxes and programers provide. i am impressed with what you have done but i really would like alot more low end power with that high reving pull you made! My hat is off to you you did a awsome job. its sad to see so many people ******* you right now. they just dont understand. i wouldnt have either without the testing i have been doing. But now i see what you have done. Most people are upset about the 150 hp claim. i would imagine if anyone dynoed this thing at 4000 rpm it would be there! What rpm do you claim that 150 at anyways? The only thing that bothers me about the shifting is the 3 to floor shift that ocurs about 37 mph it just hangs there at 35 mph at about 1900 rpm its kinda anoying. it absolutly wont shift until 37 mph period. i did notice that when you are slowing down from say 40 mph in 4th gear that it will stay in 4th even at 30 mph. have any idea why this is? can it be reprogramed to shift earlier? i have heard other complaints about this also. other than that your shifting is awsome! great job! sorry this is so long i had alot to say!

The 1704 makes great low and and top end power.
What you are talking about is low end throttle feel.
It's mainly a perception thing.
There is a map (actually several) you can tune to make 10% throttle act like 20% or 30% or 100% if you REALLY want it to.
Basically I could tell the truck if you give it 10% throttle to REALLY give it 30%.
This is simply seat of the pants.
Remember.....I'm concerned with part throttle fuel mileage too ;o)
if the pedal is too sensitive, small foot movements yield more wild throttle changes and have a negative affect on an important drivability aspect (mileage).
I spend a LOT of time on drivability/economy, etc...
You know.....I was making the HP on the 1st day on the dyno...that isn't the hard part =o)
The 150 HP gains are at peak.
If you want to do 3rd (what some call 4th) gear pulls they are only slightly off peak. Like I said, 5th is the 1:1 ratio and the accurate place to measure power. The tune also needs a few wot runs to fully "learn" by the adaptive learn process.
The gains from up REALLY high (like the 4200 you were asking about) aren't comparable to stock because a stock truck was dead after 3500 RPM. We're talking zero power output. I've got them screaming to 4200+ and I shift at 3900 or so for the sake of sanity (and it hits the next gear in a nice spot).
There are places in the curve and ot of the curve where the gains are higher than 150.....it just depends where on the curve you look.
I makes more than 450+ ft lbs over stock in some places, but this can't be used or compared! These numbers aren't quoted or advertised becuause the power curve speaks for itself... It shows a large area where it now makes power where is made none stock.
This is not part of advertising, but it is real NEW power (keywords NEW power) on the dyno sheets! Power where it made little or none stock.
New power is just an added bonus and part of the reason the trucks pulls so long and screams down the highway.
This is why getting those dyno sheets released is important.
They will be ready as soon as advertising is ready.
Advertising numbers can only be compared in places where it was making power STOCK, and this is where the 150 HP numbers came from, from the peak curve.

you're getting the rpms up where the boost starts to make horsepower....
Here are my 1/8th mile times about two months ago with the r33 predator code:
60 ft - 2.30
330 - 6.23
1/8 - 9.58 @ 73.29.

I'm aware of your numbers.
I'm also aware everyone has a different "method of testing".
Tim/Ken,
Will this article/comparison feature comments on drivability, tow files, fuel
What more could you ask for overall?

The "method" used was to line up 40 trucks and run them each 3 times and post the numbers(throw out the weird pulls)
I feel comfortable with the numbers because others were right there with me. My only problem was a split hose that let some peak boost excape which gave me a VERY flat power band.
I expect Superchips to be a good product. I have owned other chips made by your company.

I am keeping a log of this and will make a change if enough requests are made.
What is your hex code/box code?
(Or at very least your date of production and/or flash)
Which file do you not like the 3-4 shift in? (actually it is a 3-5 shift)
Are you talking about really light throttle?
Its shifting 2kisk or just over 2k at very light throttle, right?
Some say they would rather it happen at 1800 at part throttle.
What do you think?
I am still considering changing it.
Some like it higher, some like it lower....in this particular case I am indifferent (oddly enough, because I nitpick everything)

as i said in my last post it is the 3rd to 4th shift that happens at about 37 mph from light throttle. wot is ok i really dont care how long it hangs at wot thats what you want. like if you are cruising in a 35 zone it just hangs it will not shift until around 37 or 38 mph. the rpms are around 1800-1900 and noise is quite loud so it gets anoying. the wierd thing is if you are say coming down from 45 to 35 it will stay in 4th no problem even if you excelerate a little it stays in 4th. it just seems to be the upshift. my truck has a build date of 10/03 and i have the latest 04 flash with no pilot injection.

That's the beauty of three files.
Notice the tow file doesn't rev out like the perf file, but it sure grunts down low.
The Econ file is in between.
The econ file revs out a bit more on the 04 strategy trucks than it does on the 03's but still more than the tow file.
Something really funny:
I tried a number of things in testing.
This will give you an idea of how short the powerband is stock and also give you idea how quickly the RPMs come up with the performance file:
If you install the PERF trans file with the TOW or stock engine file (tuner won't let you do this, but I can do it), it takes FOREVER to get to the 1-2 shift becuase the shift point is higher than the powerband. The tow file focuses on towing power, not higher revs. The engine is DYING to mkae power to reach that shift point and just can't. It shouldn't...it's a tow file, not a race file. Do you know how weird it feels to have a really firm shift while towing? Not a good feeling.
If you install the performance engine file with a stock trans file (again, the 1704 won't let this happen), the RPMs rise so quickly at high RPM that the truck literally "forgets" to shift from 1st to second. Acceleration is too quick for stock trans parameters and all you do is (very quickly) bounce off the new 4500 RPM rev limiter.
It really took some time and finesse to get the shifting the way it is now and that is why each engine file has a matched tranny file.

thanks, jamie

These truck do NOT shift from 3rd to 4th.
It just doesn't happen.
They shift 1,2,3,5,6 (6 is OD)
4th is used for deceleration only.
But you are not the only to speak of the 3-5 shift ad preferring it to be a little lower at part throttle.
37 MPH, 1800-2000 RPM
Would 1600-1700 RPM be better?
I'd like to take a mini-poll here.
What would you guys prefer?
I don't want to go too low because then you get back into the medley of downshifting which we all hate so much.
If it's lowered too much it will upshift early, then a slight squeeze of the throttle wil make it downshift again immediately.
If I lower this (which I probably will), it will only be a LITTLE bit and only at very light throttle.

Vic,
I did quite a bit of driving today in a 35mph speed zone / speed trap. Econo file loaded in 03 cc fx4, late November 03 flash. I too noticed the 3-5 shift point up pretty high (around 39mph) at light throttle. I found myself speeding up to 40 or so to get the shift, then slowing back to 35. I personally would like to see it lowered a little. BTW, what is the update policy with SC tuners when improvements are made? I absolutely love the tune otherwise. My truck is a completely different animal, and I do mean ANIMAL!
