Wester's GMT was designed from its onset as a more secure program TC2 and GMT are close, but not exactly the same. The 2 company owners did work for one another at one time. Jet DST, TC2 and Westers GT are similar to each other. IIRC they were written by the same person, with some VDF's done by another.
You can lock TC2 files with the Tunercats Dealer kits.

How do you lock with a dealer kit?

I just finished unlocking one took me 4 days the guy was a dick and wouldn't give us the key all it was is a swap vats and emissions delete. I can see if it was a cammed or F/I deal to protect work but this was lame.I found the key then used EFI live to assign it a stock key I didn't have to license it to use that feature and you can lock them using the same deal.

I asked to TC and was told OBD2 software does not have lock capabilities. So how are people locking PCMs with TC?

I use a program i aquired and EFIlive to unlock them to assign a stock key maybe the vin tc vin match is the only thing i see or custom encrypted files but definatly not a lock.

The dealer version of the WinFlash OBDII program is a fully functional version that can read and program and all the vehicles currently supported by the OBDII Tuner program. The dealer version of the program differs in that it does not allow the vehicle's VIN to be changed and when programming a PCM the VIN in the calibration file must match the VIN currently stored in the PCM that's being programmed. This prevents the customer from using the calibration on a vehicle other than the intended one.

If requested, the dealer version of the program can be set to only accept encrypted calibration files that you encrypt with a unique encryption key so your calibration files can not be used with the standard versions of the OBDII Tuner or WinFlash OBDII programs.
