I used a guy in Florida, Mark Remmel. I had some trouble tuning my ProCharged Chevelle, also with the FAST 2.0, and he helped a lot. I'd send him my tune, along with a data log, he'd make some adjustments and send it back. We did this over a couple of weeks and he got my car running better than ever. Highly recommended, plus his prices are very reasonable. He can be reached at
