A far as power, the highest gap increase was at 4300 as well as 5900 RPM's. That increase was around 15-16 RWH. This is just a tid bit, I promise I will post the dynos soon. As far as the tune, what we were mainly able to do is clean the A/F up which made the car safe. The timing we demanded was kicked back by the ECU and I feel higher octane fuel than our California 91 garbage will help the car perform better!
