Recomendations Please. I am upgrading 2000 Chevy Express 2500 to 411 pcm. I purchased HP Tuners Suite, thinking (wrongly) that I could change the VIN. I have the correct stock tune in PCM, but for emission inspection reasons I need matching VIN. Any recomendations for someone who can do this? I am in central Texas north of Austin, but can obviously send PCM where ever needed.
Thanks in advance for the help.
