It appears you can't obtain extra horsepower out of this car without a proper tune.
So hopefully Perrin can come out with something in less than 6 months? Perrin - Have you seen the same results so far? Any thoughts?

The Solstice GXP/Sky Redline did the same thing. There's a torque sensor in the driveline that lets the ECU monitor things.
The good news is that this will keep people who mod improperly from destroying the car so badly. I'm eager to see what the tuners uncover when they rack the ECU open. One of the local tuners is going to try and download the ECU on my BRZ this weekend.
