It sounds like the Gryphon you have does not recognize your truck's .hex code (RXDE5D2). And, since you have an 03, that code cannot be a new one.

I had trans work done so the dealer reprogrammed my ecu before I bought the tuner and the tuner I bought don't have custom tunes, I checked my calibration # and it starts with a 1. The tuner came off of the same year truck as mines, I didn't update my profile I now have an 07 FX2 with the 5.4 I've been reading a lot and it looks like I will have to install pegasus and do the update, although that's all Greek to me.
