Customer is wanting me to tune his SRT4 with HP Tuners. It is an 03. I am told by another tuner you can write any 04-05 code into a 03 pcm using one of the other tuning solutions out there. Is it possible to start with a 03 pcm flashed with 04/05 code and tune it with HPT? Am I going to have licensing issues in terms of a invalid vin/os pair?
Please advise..
