The Fcon gives me standalone control which is the main reason I went down that road. Now I can adjust most aspects of the tune like cold start, throttle, idle speed etc. It seems quite comprehensive from the little I have played with it.
The exhaust was where the gains came from, I ran it in 4th this time thanks to the lower ratio diff, that's why the torque was down on the last tune.
The two lines were different boost levels, I think it lost power with more boost so we dropped it back down.
