    TPS AE is just a short burst. If it still stumbles, it may need the MAP AE increased also in that area. I booted into windows this eve and replayed your logs. Its a little rich overall but not terrible. Only other thing that stood out was a slow oscillating integrator Do you feel a surge while cruising? I viewed the log using the monitors in Tunerpro and it looks like the integrator is driving the o2 crosscounts. Usually this means you do not have enough proportional gain. Green is O2 voltage, Red is TPS and Blue is the Integrator. If you don't feel a surge, I wouldn't fool with it.
