I have an 09 CTS-V that has a lot of work done to the enigne and I am try to get the car so I can leave it in drive at the race track and it will handle the shifting. I thought I changed all of the correct fields to accomplish this but the car is still shifting several hundred rpms lower then I would like. There seems to be 4 upshift tables in the transmission tune. WOT, pattern A, pattern B and tap up / tap down. I have changed the WOT and the TUTD but still not getting the desired rpm.
