"Edevlin did you have a wandering idle?"
I never had a problem with a wandering idle, the car was running fine. We really dont know what the problem was in my setup. We actually tried several different versions of the ECU tune to try to dial it in for the 2000 2.7L Boxster with modified intake and exhaust systems.
I could have gotten bad cats or bad sensors. It could have been that I was running too rich on one of the earlier programs and buggered up the sensors and cats, could have been a problem with extending the wire or the locations of the bungs, who knows.
The ECU tune I ended up with is really sweet. As you can see from the graph I posted earlier, the torque curve is very, very flat, quite noticable behind the wheel. The tune was optimized not for max hp, but for responsiveness.
