I'm in the Pontiac area.
My experience with AMS and Uprev has not been as expected. the initial tune Uprev sent me had idle problems. I used their stock ROM with patches and it was fine. The tune I got in Chicago exhibits throttle response problems which AMS and Uprev are trying to resolve. I trust it will be resolved, I'm just a bit disappointed.
Anyway the tune netted about six RWHP and about the same in torque. I bumped the rev limit by 300 and had the speed limiter increased. I have a tuned map, economy map, valet map, anti-theft map, and a stock map. I was charged one hour of dyno time and my wife made me buy an AMS tee shirt.
