Yes, changing the throttle body will change your tune, and be kind of counterproductive to the changes that you have already made... You can think of a tune in terms of a race that you have just finished... You raced to get the ideal parts for your car, and you finished them by tuning you car to those particular parts. The best money that can be spent on your car is...

Hypertech "Max Energy" Power Programmer

its right around 350 bucks, and will pay for itself over and over.

Will I lose hp do to the way the car is setup or will my car gain hp. Any help would be great. Also what is the stock fuel injector size on an 2004 GTO.

The stock injector size on the 04 GTO is 26-28lb/hr. Also I don't think you are going to hurt the performance of your car by putting a bigger TB with a tune. I put headers on my car after the box tune did I lose power nope but if did feel alittle stronger, and yes it needs to be adjusted some. In your case, wait till you do more mods after the TB before you spend $400 something on a new tune.

Does anyone have one in their GTO?
