Invalid Vin/OS Pair Error message on already tuned PCM

I've sent an email out as per instructions, but my question is this; the PCM has a wait4me tune already on it. Am I getting this error due to the tune? If so is there anyway to fix it on my end?

Also I installed 2.23 Beta and it took the application key, but when I tried to go to 2.22 suite it asks for the application key and says it's invalid. I'm copying and pasting it directly from the email.

Having the pcm flashed to a valid vin/os pair via tech 2 & then rereading with our software will usually work.

The tune you posted has a 2003 VIN and a 2006 OS - you need to change one of these. The VIN (year / vehicle) must have a corresponding OS originally offered in that year, with that vehicle platform.

Thanks for the reply, Im guessing the only way to fix this is to find a tech 2 and reflash it? Like mentioned in the above post.

You have a couple of options. A full reflash to stock with a Tech 2 / Tech 2 type device - from a GM dealership or tuner who owns a Tech 2 / Tech 2 type device.

Or, given the VIN OS mis-match, the PCM has already been flashed with non-HPT software. Take it back to where you got it - and have it reflashed with a matching VIN OS combination.
