I have a VCM Suite for a 98 GTP.
Please explain to me the OS # requirements and VIN requirements for this to work with my PCM.
The original PCM from my car was used as a core and prior to the HP Tuners I was using a DHP which I know cannot be used since the OS was set to 0. I sold my DHP and was supposed to be sent a stock 98 PCM as a core. I was sent a Grand Prix Store PCM, OS of 0 as well.
What are my options??
