F1 tuning claims 30% hp increase, 40% tq increase, you believe it?

Thats alot imo no? 25whp horsepower for less then $500? Where else can you get that?

Mail-order “tune” for my car is $50

Granted it’s just a rescale for the bigger turbo/injectors that I’m putting on it, but I should make another 150whp
