I tried to PM you directly, but the system will not allow me to, based on my new status.
I know there seems to be an issue with the Bonneville GXP PCM. (4.6L Northstar LD8), But I have been told by another company that upgrades the tuning on PCMs that they are going to have programming with-in weeks. I'd rather not use them as they do not know the Northstar setup like you guys do.
Based on your connections, I was hoping you had cracked the code and have some good upgrades for my GXP.
The PCM number is a 12587465.
Any info would be appreciated.
