Now that the XDF is out for the 6HP28 and 6HP21, what are all the possibilities we could see beyond what @RayBan has shown us in the OTS maps? TCU tuning has never been an option for this platform and I think there are a lot of intelligent people who have something to contribute. For example, how involved is it to simply raise the shift points up to say, 7500? How much extra stress does this put on the transmission, how is that calculated?
