My build is 3 years old and was working great untill the latest hp software download. I'm running a 4l80 transmission with a full manual valve body. When loading the tune before I had to change the transmission option to 4 speed auto and disable the rest to get everything to work correctly. I updated the software and changes a couple trans codes to get rid of the check engine light and when I reflashed the ECM I now have no throttle. I can see the pedal percentage go up on the vcm scanner but the throttle body doesn't do a thing. I have since reverted back to the original file and still nothing. The truck worked fine up untill I updated the software and tried to load the new file. Literally nothing has been changed other then the file update. I've tried going through all the available trans options and reflashing it with no luck.
