And using your last dyno plots at Champion as reference point, it would tell me that the Cobb tune is making about 40-50ft/lbs of more torque to the wheel than the GIAC (I'm simply subtracting your new torque output with the intercooler/tune with your old output 559.73 - 515.74 = 44 ft.lbs). Just to be clear, I'm talking about GIAC Stage 2 vs. Cobb Stage 2 only.
Now the interesting bit will be to compare your car (Stage 3) to a true Stage 3 Cobb car in the coming race!! I think everyone on this forum is interested in finding out the results

Great stuff John, you've got an awesome BEAST right there! I recall your days earlier this year at Limerock with the C4S that didn't run right and went off-track...this 991TT w/ COBB would obliterate the field at any track! Excellent stuff!! ...and thanks sooo much for the pictures (of the cars that is)
