Was tuned by Jorge back in mid-November but added aquamist's HFS-3 water injection and koyo radiator for this tune. Ended up getting 366 whp and a whopping 379 ft/lbs of torque at 25 psi on P&L's dynajet. That was a gain of 44whp and 74 ft/lbs torque over the base tune. Jorge put on an amazing tune with attention paid throughout the powerband. We chose to work on partial throttle response as well as WOT. Had to compromise some a/f ratio at WOT in order to be aggressive in partial throttle but that's where I spend most of my time driving as I only do brief WOT pulls every so often. Car is tremendously fun. Guys at P and Motorsports are great. Aquamist kit really did what it was suppose to.

Here's a couple pics of the plot:

Hey Gerry! Just caught this! Glad the car is running great, and just saw the comments from the Aquamist guys on their forums. They are very kind with their praise!

Let us know if we can help you with anything else!
