Hptuners and GMPP e67 ?
I am getting ready to purchase VCM suite. and have a few Q's.
So I see you can tune the GMPP e67 with Hptuners. What I am wondering is, do you need the Tech II to write a vin to it? Or can you write a new Vin with HP tuners..
If i had to send it to someone it would not be a problem.
I am on the fence for GMPP LS2 harness with HP tuners.
or a Current harness and ecu. but then I will need to buy HP tuners anyway. planning on F/I
but if i could Save $500 I would love to
