Gryphon worked great on the truck with the old calibrations, with the newest ones that were released updating the driveablility for two flash series (Cant Remember the letters right now), im running higher egt by almost 200-250 and the transmission is not shifting very well under heavy load. From a dead stop it will sometime not know what gear to go into. From a roll no probelms at all. Stock tune no probelms, old calibration no probelms.

Any Ideas??
