4.3/4.8/5.3/6.0/6.2?
What cam?
What converter?
2wd or 4wd?
What gears?
Big tires?
Rcsb/ecsb/ccsb or even LB trucks?
Is it retuned for the new parts?
Service engine light?

A ton of info is needed to dial in an issue

5.3 tsp228 cam, long tubes, 3000-3200 stall, 4.56 gear it may need more tuning it drives around great and pulls hard but from a stop to 3k rpm somethin is holding the truck back. my buddy went for a ride with me and he said it felt like i hit the nitrous once it got over the 3k rpm

You should pull outstanding with 4.56 gears and that stall providing that you don't have 35> greater size tire. if you are running factory 31" tires your be burning through first gear i.e. pure tire smoke.

IMO you already invested a lot of money get someone who tunes and is recommended by the forum to tune your truck. guessing at stuff is not gonna get you where you you need to be.
