aight so ive done some research and ive decided ima get a trifecta tune, but can anyone please explain to me all the pros and cons of it. what all i can control with it, and how the trifecta tune works please

 

Basically you tell vince what your goals are for the car/tune, and vince emails you a tune file. Then you data log, and send vince the results, and he'll send you a revised tune. Repeat this process until your tune is properly dialed in. It's better if you just rent the flash cable from vince so you don't have to rely on a dealer for a retune. As for what you can control, you can get a switchable tune, so you can change between 2 tunes at the push of a button. You can also change the rev limit for launch control.
