2012 GT Will a Bama tune void my 7 year extended warranty. And is the performance gain worth it.
I'm no expert but I find that really hard to believe! facepalm2.gifI too am having this dilemma. When I had my BMW 335i, the tune alone gave it another 100hp (look up n54 engine tunes) so for me, that was worth the risk as the extra power made the car into an m3.
