wow that's quite the ride you got taken on there! I dealt with Monty from JMS through phone and email and everything was great. I had my car previously email tuned from Tasca and couldn't stand it. My RPM's would drop verrrrrry slowly and I hated driving the car. The tuner told me that was the best he could do. Monty had it fixed with one email tune. Loved it ever since. Trust the guys that have a proven track record and you'll be fine! Good luck!
