if you did all that and you have no go it's from the transmission slipping and the ecm defueling, time for an upgrade.

 

[JClaflin]

ngm but i should still be able to feel the differance in the change if im not getting in heavy right or that much of change demanding that much more fuel to act like it is thanks

 

[BigDan]

I didnt feel much of a seat of the pants difference when I went from my tiny stocker to Silverbullet. About the gears..... ehhhh I dont know much about that but I also wouldnt expect much from that as far as seat of the pant feel in HP just quicker reving.



Turbos dont really add as much seat of the pants hp as electronics, it just makes it more effecient and the ability to us a TST... .

Maybe with the lower gears your not loading the motor as much as you were before

 

[bmoeller]

Why the 4. 56 gears, bigger tires? That will definantly hurt the "seat of your pants" feel.



The stock autos aren't that great. Poor power transfer (mainly the t/c). My stocker was slipping so bad, that when the new trans went in, I gained 10# boost. No bull. Went from 30# to 40. Was finally able to get the power to the ground.

did you say all thaty in one breath?

 

[RobertP]

if you have a 03-04 the hot juice will give you around 500hp with a turbo and your injectors should give you more, also you have a intake and exahst, your well out of the range of your stock auto, you do need to upgrade. suncoast is a good and reliable choics for built trannys.

EXACTLY WHY THE 4:56 GEARS, I HAVE 37s AND 4:10 AND ITS STILL TOO LOW FOR SPEEDS OVER 85 MPH WITHOUT REVING THE HELL OUT OF THE ENGINE, I WISH I HAD 3:73 WITH THE 37s, MIGHT NOT BE LOADING THE ENGINE NEAR ENOUGH WITH THAT LOW OF GEARS

 

[JClaflin]

yes guys 4. 56 because of tire size 37s on 22. 5 wheels very heavy and i also tend to pull a little wieght 10 to 15 thousand lb so if that is the case that im not loading up enough what next then mabey a smarty you think

 

[JClaflin]

sorry guys the truck is a 04. 5 3500 dually auto

 

[Forrest Nearing]

probably not loading the engine enough... my sps62 with a 6sp, 35's and 3. 54 gears doesn't start getting "fun" till 4th gear... only have a 3000rpm to play with right now.

 

[Summit]

when i put in my gears it would pull way better not to mention easier on the stock transmission with 37's, the twins was a big difference. sure you dont have a boost leak or are wastegated too low. if the transmission is slipping you'll know watch the rpm's.

What size is the exhaust side of your sps 62?

 

[JClaflin]

hey summit how do you check to see if my wastgate is to low thanks

 

[Forrest Nearing]

What size is the exhaust side of your sps 62?

only size they offer. I will say that my truck is a 12v... they spool slower than a 3rd gen
