I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

I am having a problem with getting a P1825 code. Mode switch invalid. My snapon versus pro states 0 ignition volts and all swith status high. temp sensor reads -40 Changed mode switch, did the testing as ALLDATA suggest with grounded jumper.No change in status. I have voltage at Terminal 5. Ignition volts at term.12 aynd 12 volts at serial wake up term 9. Ground is good as my BCM locks and unlocks doors in park and with a volt meter and test light.Tryed a second TCM What am I missing? Car ran good before I started to add a wire to term 7 for tap shift. Anyone? Thanks Paul
