I'm glad you love the software. I thought the car was an entirely new animal once we flashed it with the last tune. I would also highly suggest powertrips exhaust setup to anyone - it sounds like an F1 car and makes great power.
mixja: Stage II makes more power than Stage I. We do claim a power gain on the Stage I to Stage II software. The added exhaust flow allows us to manipulate other values to increase horsepower and torque. Powertrips car was very strong - putting down that much power in that kind of weather is not easy.
We just became sponsors of the board today so please stay tuned tomorrow for the full writeup with dyno's, videos and pictures of our shootout event today. It also includes an AA Supercharged M3, and a 2009 SL65 Black Edition as well. Feel free to contact me via email or phone regarding the software.
