I love the experience I have had. I cars is day and night faster with no check engine lights or any issues. The customer service is next to none. Always available or calls back when I need something. Plus they tune and check my logs to make sure my car is good, not just tune it and forget it type. I would highly recommend them
@OK CANCEL Actually I'm interested too. I've been running hard without issues, but if there is something we should be watching out for please share specifics so we can be aware and protect our cars.
I run high 11 second quarter miles with my heatsync stage 2 plus and that’s in a 2011 750i 12k miles with the tune running strong anyone who said to stay away is a hater or sergey dick rider
