Target Throttle Plate Angle (Only changed above 6400)
Ignition Timing Post Start (Cold Start Adjust)
P0420 Code is disabled
The Stage 2 has, in addition:
Open Loop Fueling (Richer at high load low RPM, Leaner at high load high RPM)
LTFT Limits (Reduced to +/-2%)
Base Timing B (Less Timing at high load high RPM)
Knock Correction Advance (More Timing at high load high RPM)
Timing Comps Per Cylinder A & B (Now all 0)
FBKC Range (Enabled now set above 3k RPM)
Intake and Exhaust AVCS Changes
The AT is pretty much the same as the above, just no P420 defined and P0700 code is disabled.

Confused as to what makes an aftermarket catted header different than stock header. By stage 2, do you mean stage2+? Could one theoretically run stage2 on stock header? Maybe with the avcs tables from stage 1 since it's optimized for stock header?
