550 ECU TUNE QUESTIONS
Hey guys, I need a bit of help. I was thinking about taking my 550 in to get reflashed at OE tuning and I need some Advice.
1. Anyone receive any problems from this?
2. Warranty issues? would i have to relash to original if i decide to take the car in to the dealer?
3. How are the gains? Will I feel much of a difference?
