Okay, I'm looking to flash my 2008 dodge charger 2.7's PCM with B&G. I have a spare PCM that I bought on eBay, the donor car was also a 2008 2.7. I swapped it with my stock PCM to see if it was functional, the car started then shut off right away. When I put mine back it, it was back to normal. When I called B&G to ask more about the flash, I asked the guy if it was possible that my car didn't start because the VIN# on the spare PCM was different and he said yes. Anybody else hear or experience this? I just don't wanna send it in and pay for the reprogramming and flash to find out that's not the problem and be screwed. Anyone???
