I have a licensed 04 S-10 auto blazer PCM that is going into a 03 S-10 manual truck an i am wondering about the vin change. I all ready know the vin is not going to match an would like it too. I assume i can program the 04 pcm to the 03 truck to change the vin but will HP still recognize my tune when i try to copy an paste parts of my tune back on the PCM or will i have to re buy credits to license it. Sorry for the noob question. I have access to GM TIS/Tech2.
