My two-time experience with Stephen and England Green is that their tuning made 30 rwhp and associated torque disappear from my 2008 Z06. After that experience, 510 Racing correctly tuned my car and brought the hp and torque back. Since that time my car has been run on Texas World Speedway and Circuit of the Americas and Harris Hill Raceway and has been proven to be a 100% safe tune. I asked Stephen at EG to refund at least a portion of the $550 I wasted at his shop, and he has refused. So if you want to waste money and have less power to show for it, be sure to go to EG. Tell Stephen I sent you.
