05 Sierra 2500 4l80. Trying to tune the VE table and I cannot figure out why I'm getting max line pressure on shifts. My OS does not have the pull down to shut off max line pressure when the maf is failed. I've done quite a bit of reading but the threads seem to die off without resolution. Does anyone know a fix for this?

Contact support at HPTuners. Connect and get an infolog from the ECM. Send them that along with your current calibration.
Thank you. I will update this if anything changes.
