valid HP gains?
I recently saw in a "popular performance shop" catalog some "package deals" that listed various HP ratings. I would like to know how accurate they are;
Intake and TB = ~25hp
Intake, TB, MAF = ~ 35hp
Intake, TB, MAF, 1.7rr = ~45hp
Intake, TB, MAF, 1.7rr, Heads = ~75hp
all above + headers and cam = 100hp
Keeping in mind this is for a bone stock engine.
