I understand you can't tune it, that's why I'm completely swapping out everything. Computer, engine, tranny, suspension.
The only thing you can do to an 08'a is a CAI and an exhaust, maybe squeeze a few Mg's out of it. They can not be tuned. Because tuning is required for everything from a 180 t-stat to a turbo, you are stuck. Either get an older GP or get used to being slow.

Hmm, Overkill seams to be able to... sooooooo
You can make easily 500whp without tuning it... An afc goes a long way.
