Engine Tunning Anyone....?

[The Stang GT]

I was just wondering if you buy a tuner from diablo and the likes and it is setup for a stock GT, what occurs if you decide to modify the stock monster after recieving the tune, do you loose the gained horsepower and torque....???

When you get the diablo tuner it comes with a pre-set diablo tune, that will give you some more power, and you have a custom tune. You can modify parameters on the tuner such as shift points fuel etc so yes, whatever you change is changed. ex. Bump up fuel pressure=bump up fuel pressure. I wouldn't suggest doing it unless you know what you're doing. Dont just go into it thinking, hey I think I'll see what this does.

What are you planning to modify? Bolt-ons? Cams and other internals?
