To me, it seems as though there are some inconsistencies in hp received from mods performed. I myself saw a 20hp increase from headers/xpipe alone and once tuned saw an additional ~5hp increase across the board with the same peak numbers. Then, you read about a guy verifying 30hp from headers and an additional 20-25hp from a tune. Read about another car getting 30hp total from headers, full exhaust, cai and tune. Watch the jlt videos and see a stock car get 30hp from their intake and their tune but I believe most of those gains are from the tune. Then there are people bolting the intake on and only getting 1-5hp tuned. It just seems to me that the numbers on our cars are all over the place. Given the research I had done, I expected to gain a conservative 15hp from headers (got 20) and another 15-20hp from the tune alone yet I didn't get it. And before some says sae vs std or one car versus another, the examples I am referring to are apples to apples. For me, I have a hard time believing that there's a huge difference between Lund, AED, VMP, Livernois, Revolution etc tunes other than drivability and maybe a few hp. I know I'm not the only one to notice this, what's your take?
