July 2011 dyno test run after APR 93 tune. The weather wasn't the greatest, about 85F and humid for the "after" runs and 75F for the baseline runs. The best numbers I got before and after: Before tune - 444 AWHP After tune ---- 474 AWHP Thanks to the guys at VAST performance and MotorCitySpeed. They were all great to work with.
