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.

I had the same problem with my Camaro shifting at 5600 RPM with the WOT RPM set factory set at 6000. I found the WOT Shift Speeds changed it. It was set at 28 MPH stock and 31 made it shift at 6000, and 32 at 6200. I have the WOT RPM set at 6100 and WOT speed set at 31MPH and it shifts at 6100. Hope this helps.

Post the trans file and lets have a look!

Good point Ron, make sure the part throttle shift tables are setup properly with regard to RPM as well as speed.

OK. I am very new at the EFI live. I used to have an outlaw TT camaro with a Felpro but this is way different.
