Latest update. I squeezed a bit more timing into that flat spot. Feels stronger, no knock in that area. HPTuners is showing slightly over 600 hp from 5400 RPM and up.
I'm feeling really good about the tune now. Cant wait to get it to the track.
An interesting note... I was having the A8 shudder with the canned tune... once I bumped up the VTT values... I no longer have torque shudder. There's still a constant 200-300 rpm up-down every few seconds, which I think is the lockup clutch slipping? But the rumble-strip vibration is gone. I think what's happened is that now it unlocks the converter at lower pedal input before the shudder happens. Going to look at doing fueling and torque conv over the winter when I wont be driving it much anyway.

Track times are getting short at Gateway since every weekend has an event. I'm going on the 6th for WOW to get some runs in and see if I can run 10.70s with my bolt on C7, should be good DA and lower temps.
