The 1704 does not require exhaust upgrades, though I always feel every diesel should have gauges (stock or modified) and exhaust is just a smart upgrade.

Contrary to popular belief, many trucks (particularly those with manual trans) have EGT problems STOCK...especially with the ideal gear is not selected (very common) and excess load is created for long periods of time.

 

Well, just got my motorhaven account so I can order, but one 'operations' question. With the 1704 programming, is there still a use for the tow/haul feature on my 04 f250? Is that button at all useful with the new tune?

 

Skippyp, this information has been covered before in this thread.

If you use the search this thread button at the top of the page and enter haul, or tow, and so on you'll be presented with a wealth of info on the topic.

But in short, yes the T/H mode sill works with the 1704 and is useful with the new tune.

 

thanks DH- I missed that post. I'm gonna start dumping these things to the printer so I can read at meetings. More interesting than work, anyway.

 

At 23 pages it's easy to miss something

It is funny, sometimes I'll be on Google doing a search for something related to the truck and it will point me back to the ford-trucks web site and sure enough the answer was here all along

 

HOLY MOLY! What came out of my mouth at the time was something else. I felt like I was in a mustand gt 3 feet in the air!

Found a local willing to uninstall his and let me try it (cost me a bbq dinner). Put it in economy mode.

run #1: 2wd on patchy wet pavement. Started out like factory and then heard the turbo wind up and BLAM! I was moving. First shift point was too soon and very rough, as were then next several gears. Rear end broke loose a little so I backed off. Foot never hit the floor, I'd estimate 75% pedal.

run #2: same setup- shifting still horrible, but I knew what to expect from the power.

run #3: 4wd. Wimped out a little here. First shift point was a small jerk- second chirped the tires. I could hear the front axel and continued to hear it after coming to a stop (is this normal?).

Turned off 4wd (still hear front end) and pulled into a parking lot. Turn off ignition for 15 seconds or so and then restarted.

Next 2 runs in 2wd were much smoother. runs in 4wd were also better, but I still don't know what to expect from the front end- sounds totally different than my 99 expedition 4wd did.

observations/questions:
1. is the new tune relearning the tranny shift points? does that explain the whiplash shifts on the first couple runs?
2. who in the world is running on hi performance? do you wear a helmet & diaper?
3. the switch from 4wd still left the front end grinding- is that normal (probably not related to the 1704)
4. the truck actually got louder and a little rougher at idle. should I have expected that?

I'd sure love to hear some thoughts on my reactions.

Honestly, I don't know if I'd want my wife trying to accelerate onto the highway with the kids and get hammered like that. The power really sneaks up on you. I've heard the predator is stronger in the low end so maybe that would reduce the sudden power onset. Of course, no one around me sells the predator and says I should either get a Banks or settle for the superchip (hmmm, $2200 or $400?).

 

The superchip has a longer powerband and is stronger at the high end on the PERFORMANCE program. The Superchips is stronger at the low end on the tow program (especially when under load).

You'll need to drive the truck for a few key cycles under numerous conditions (load) and let it learn.
If it still shifts too firm, I can soften it up.

 

Don't "settle" for the superchip. The superchip is the all around best quality product. If you have an issue, I can make necessary changes.

Shifting is a funny thing. What one person thinks is just right another thinks is to firm and yet another thinks it's too soft.

It's all point of view.....

For instance, you don't want your wife and kids in your truck on performance mode....others can't get their truck back from their wives =o)

 

Hey Vic. Don't misunderstand me- that was the dealers pushing the banks over the superchip. As I mentioned, they push a $2200 package- so they're just after the cash. From what I experienced last night, I don't see any reason to do more than a chip.

As for the shifting, I only gave it a few starts, so perhaps it smooths over time. I haven't read anyone else having their truck buck like mine did, so it's probably just an initial thing.

thanks for answering questions!

 

Was it dropped or anything?

Sounds like a simple hardware issue.

Get an RA, send it in and it will be replaced at no charge. It will be evaluated, of course to make sure it is a hardware problem.
Regardless, it will be resolved and you will get a 1704 back at no charge.

 

i love the new superchip.....and WOW will it throw something off the dashboard....ive had it now for a month....ive used all 3 modes but now have it in ECON. and more than likly thats where it will stay...i know the shifts were gonna be stiffer but didnt think quite so stiff....been a few times its knocked stuff over in the truck....i guess this all ends up getting to a question.....will un-installing and re-installing do anything at all?...thought about it but figured i might ask first.....and also should it feel like a double shift feeling when it goes from maybe 2nd to 3rd? just questions from a not so great mech.

 

As for the Front axel making noise a 4x4 truck like ours is not made to run in 4x4 on dry cement (wet ice snow dirt only) it will tear the system up. The people who run it at the drag strip in 4x4 run it in a perfectly straight line and should turn it off before making any turns at all, hope you didn't tears yours up......Tim

 

If the shifting is too harsh for you, call superchips for an RA and I will soften the shift at part throttle.

 

do i need to re-set it to stock setting before returning it?....so its normal to feel the double shift feeling at a low throttle? and im saying doulbe shift but its more of just a pronounced shift...more than the other shifts at a lower throttle...jerky might work....sorry if im not making much sense....just trying to learn....and thanks for the response Vic.

 

It does have to be set to stock before returning it.

Sometimes it will skip gears when upshifting at part throttle, this is normal and Ford intended it this way.
If it feel goos to you, go with it.
If you feel something isn't right, get an RA number from superchips so I can look at it.
