Attempting to tune a 2012 6R80 with a Boss intake up to 7,500 RPMs, but not getting any higher than 7,200. After making multiple adjustments, we discovered during data logging that with the pedal pushed to the floor, it's only reading at 80%; 85% if I take the floor mat out and lock my knee into it. Could this be causing the car to shift early? How can I get the car's WOT reading from 80% to 100%?
