I added the Hypertech with other performance items so it's hard to tell exactly how much it helped but it has increased HP and throttle response. I can only change the rpm limiter and top speed, I really would like to adjust the speedometer for tire size and gear changes. I understand why I can't, just wish I could. Performance was my main goal so I'm happy with it.
