No regrets here. I was an early adopter, had my tune in August of 2011. My engine did fail due to Turbo failure and pistons cracking at around 23,000 miles in March of 2014. I can't say it was due to the tune. I rarely went out of ECO mode. It may sped up the inevitable, since the 2011 had piston cracking issues. I did reflash to stock before taking the car to the dealer and never had any warranty issues. In the early days when I had an issue with the tune, got a one or two day response from Vince with an update. Hey, the car is gone and loving my new ride, so no regrets, just a monthly payment now. Never thought I would be driving a BMW.
