Got my tuning done on saturday at GRC Performance in Mission Viejo, CA. Was running the 91 octane Diablo tune with my Mac straight shot and axel backs. Didn't get to do a stock pull, or pulls as I added the mods. But based on other stock numbers from the forum, most getting 255-260 RWHP, it added a solid 20 RWHP. I can tell a good difference in how the car pulls around 4k. If anyone would like a copy of the tune let me know. It is based off the steeda tune, but Im not sure how much was changed.
