Love it! Justin has tuned my GT500 as well and he is always spot on with the tune. The auto tranny is not easy to tune, and when your on the throttle it will break you neck when it shifts, and when your tooling around it shifts soft too. This tune when it shifts from 3 to 4th at 80mph will break the rear tires and amazes anyone who I have taken for a ride.
