My setup is a stock T2 motor and turbo with the sds, 4x720cc injectors, msd ignition and boost retard, and i think that's all that matters. The problem I running into is that when using a linear map values my motor goes very lean around -10 during a satined condition and light acceleration. to counteract it I have to increase the map values by 7 to 8 in that range which seems like alot. Also during warm up the car is far to rich and It has nothing to do with the engine temp value. Are the air temp values tunable?

found out that the root of the problem was not ecu tuning but a poor vacuum line connection causing a pulsating in pressure... go figure.
