just doesnt't seem right.

i have tried just about ever electronic on my truck and had no luck with anything except Smarty 411, the REVO even sucked compared to the 411.

anyways, i sold the smarty last night so i came home and put my 4" factory exhaust back on (minus the muffler) and it seems as if my truck runs GREAT now!

shift points are dead on, wayyyyyyy better MPG's, and ALOT better spool up.

anyone have an explanation? i've sold all of my aftermarket parts and am back to all factory.

sounds like you were hitting it with too much fuel

Maybe that truck just doesnt like to be modded.

So what exhuast did you have on before?

Im guessing you took off the 5"?? I bet that 5" straight did hurt your performance at your performance level. I remember when I first totally straight piped my 05 with 4". It lost spool up and seemed to lose a little power. I bet thats really the case with that 5" turbo back no muffler no nothing.

no i got rid of that 5" i got from you a long time ago (march), then i had to steal it back. i had a 5" from the DP back (4" DP).

i'm thinking this truck just doesn't like mods, time for a damn 12v

yeah, on a sub 600hp truck, I like to run 4" pipe at least to the back of the cab
