Horsepower after Full Bolt-Ons and a Tune?
I had a friend ask me this question, and I couldn't really give him a good answer.
On average, how much horsepower and torque do our cars make on full bolt ons (Intake, Exhaust, HFC/TP/LT Headers) and a tune (probably Uprev)? Obviously, we can't just add the individual horsepower gains of each mod, it's gonna have diminishing returns.
