The speed and power gains were extremely noticable. Worth the money.

The programming was easy. I turned off the AFM to test the claims of other reviews that actually increases MPG, that's BS. MPG actually dropped. However there is a nice increase of hp. The dyno rating are on Hypertech's site. I will be turning AFM back on though.

Missed out on AutoAnything $50 rebate by 4 days:(! Make sure to have battery booster just in case. Bullydog updater not compatible with Mac, took multiple attempts to get the new download to the microSD card or for the pc to recognize the card.
