How much would a custom tune run for my car. Money wise and how much HP would i stand to gain.

 

Full custom tunes can run anywhere from $250-500 depending on the shop and what they actually need to do. The big question I have is why do you want a custom tune? If your car is fairly stock it will not be worth the cost. On a near stock car you might pick up 10 hp if you are lucky.

 

Do you already have a flash tuner?
