It seems to me that running rich at this point in your testing is a "Good Thing".
Are you tracking DI FRP? If so, how is it holding up? That was always my biggest fear. BAP and Methanol Spray helped, but I still always worried when lambda spikes might show up.
How do you keep the AWD system from shutting everything down?
The night I got my 12.904, I had my system shut down on 9 of 12 runs. Always happened at the top end of 1st. When I left it floored, it came back on with a .5 loss in 1/4 mi time, but little effect on speed.
That's when I went to the front Nitto 05R DR's, which at my performance levels solved my issues.
