I gave a 4 star on overall rating due to the fact that when I first installed the tune it didn't run well at all. After getting with customer service at Hypertech problem was resolved with an updated program. Now car feels noticeably more powerful thru the RPM range and has better throttle response. Really liked that tuner is able to adjust for three different CAI and has adjustable speed limiter also adjustments for cooling fan and RPM limiter. MPG seems to be about the same as stock.
