'03 F250 6.0L 4x4 Crew Cab. With reflashes done and everything stock except 315/75/16 tires and 3" lift. What is the easiest way to get good bottom end. I tow a 5k lb trailer on occaision but mostly concernd with daily driving. I really hate how you have to stand on it to get the power going.

I'm sure this topic or similar has been discussed in great length so I apologize for beating a dead horse but I don't spend much time on the computer to do a thorough search.

Any help is appreciated.

 

Get a chip. It takes the lull out of takeoff. You should probably get gauges and exhaust too though just so you don't do damage.

 

Get a Diablo Sport Predator here from the friendly folks at Motorhaven. Best plug and play program going. That is assuming yo don't have some other problem. You will have a little turbo lag unless you do other modifications but still need to get to 1500 RPM to get the turbo spooled up.

 

SBV is usually right on most things....
but I've noticed since dsconnecting the EGR and using the predator's +65HP mode that there is minimal if any turbo lag !!!
Or at least the violent acceleration created makes me scream "What turbo lag?" as it's snapping thru the gears....

The best part of the 65hp program is that you CAN experience an improvement in mpg...
I saw CAN, because you CAN find yourself grinning from ear to ear too much when you give it 1 inch of throttle and it ZOOMS !

I would suggest you also consider changing out the restrictive (and VERY heavy) stock muffler for a better flow thru design or consider a cat-back or turbo back for even better egt reduction and performance...

 

I know I should probably know this. What is the EGR and why disconnect it? Ramifications?

I've not had any bad results of doing it...

 

Nobody has said anything about the superchip. How does it stack up to the Diablo. I just ordered the superchip last night and I feel confident I made the right choice. I know the superchip helps with shift points and the diablo does not. However the superchip makes a little more hp and torque. What say you all?

 

Don't know about the Superchips; but the Predator works as advertised on my 2004 Harley edition. I'm very happy with it.

 

We didn't say anything about the superchips because we didn't want to lead him down the wrong path well not than it's the wrong path... just that there's a BETTER path
to each his own.. and I hope you enjoy it - anything is better than stock !
but
the predator was out and running fine WAY b4 the superslip came out...
the predator makes more HP than advertised...
superslip STILL hasn't posted a true dyno graph because the numbers are disappointing and not making their advertised claims... and so how can it make more hp and torque...
My dyno sheet is in my gallery... We have asked for many to post their dyno sheet with the superchip, but none have that I recall...
the only thing they've posted are a hand typed spreadsheet like thingy...
My 8 year old can fake that

But REALLY, if it DID increase HP by 150 and torque as well I'd be interested in it... but thus far I've only seen less than that... on the dyno and on the track...

the shift points are not adjustable on either if that's what you mean.. but the predator was the first module/programmer to get the 2 to 3 shift right at anything approaching +100HP... I know... I researched them all...

and if I recall, the last poster said the superchips torque numbers were about 100 ftlb's less than mine.... and above 3000 rpms....

check out the dyno sheet in the gallery and you'll see some fine numbers...
(and mine was not the highest numbers on that day !)

 

I guess anything is better than stock as you say. I will have to see how it performs. Thanks for the input.

 

The Juice/Attitude combo is pretty potent also. You can adjust your fuel at low boost compensating for the turbo-lag the poster was referring too.

 

Looks like I'll be checking into a Predator and exhaust system.

 

To be quite honest, I still notice a little bit of lag on mine at startup. I have the 6.0L 2003, and the Diablo tuner. It wont spin the tires immediately after I stomp on the gas, but after it gets up to 5-10 miles an hour and the turbo is fully spooled, the tires start squealing all the way to second. If I do a little brake stand, then I can squeal the tires from zero mph, but that is kind of cheating

 

it is still gonna be a dog at take off, no matter how many chips, or tuners you throw at it. the turbo WILL NOT produce enough boost at tip in to move that beast. i would wager that a predator on the highest setting will not get you more than a couple pounds of boost lower than 1500 rpm. you might get a half second less turbo lag, but not enough to really make a huge difference.

only one way brougham, and thats gears!
they will get the rpm to the boost threshold ALOT quicker than stock. the boost threshold is the minimum rpm in which the turbo is ABLE top produce boost, it is a function of the turbine housing, and turbine wheel, and thus no amount of over fueling is going to make more than a minute difference.

toss some 4:30's in it since you went with a 35" tire, that will get you a slightly better overal first gear ratio, and will get the turbo into it's operating range MUCH quicker than it is now. if you do little highway extended trips, then go 4:56, or even 4:88 and watch the tire smoke in your side mirrors
wish i could afford it, id have 4:56's and 37" tires in a heartbeat.


good luck

 

Typo. Sorry guys
