well recently i got new headers, exhuast, tune, stall, and trans. whith all these on the truck has no topend at all. when i punch it from anywhere from 70-90 it takes forever to top out the speedo. i know i know, i shouldn't be going that fast. but anyways.

old exhaust set up: edlebrock shorties to factory catless y pipe. factory y-pipe back with muffler swaped out to a 3inch in dual 2 1/4 out with 45s out the back.

New exhaust set up: pacesetter lt and y-pipe. factory y-pipe back to a new 3in in/out hooker areochamber dumped over the axle.

would this exhaust setup flow more and cause me to loose A LOT of topend. or could it be once of my other recent mods.

i also got a retune from nelson and they didn't have any of my old tune info because they switched softwares since. so i told them exactly what mods i had, and that i deleted my egr and cats. could it be my tune that is causing my loss in topend?

what could i do with my current set up to get back my topend? please help me out. thanks

i would think tune but you have done a lot of different things to really pinpoint it. you should have a lot more topend even without a retune imo.

 

If any thing your highend should be better....maybe its just the feel from the verter making it seem differant...

 

i defently thought the topend would have been better too. but i was wrong. if it is the tune what would need to be changed or looked at. im not sure what exactly nelson changed.


nope defently a noticeable loss in topend, i noticed it and my buddy did too, the speedo doesn't climb like it used to. the topend was one of the things i loved. i could acually screw with people on the e-way, now i get left in the dust.

 

oh also i noticed when im on the highway and it drops to third the RPMS stay right at 4200 and climb really slowly, im not sure if it did it with the other stall but it really caught my eye.
