Dear EFILive,

More than a year ago I had to replace all of the computers in my 2500HD. The reason for this was because I had some engine issues (related to the environment, not the programmer). I had to replace everything on my truck to make it stock again. It has been under warranty again, since then. Now that I have more than 100,000 miles on the truck - I am no longer under the warranty anymore. That being said, I updated my AutoCal from PPEI. When I tried to tune my truck again, I got error code $0533. PPEI told me that due to the fact that I have all new computers on the truck (same VIN # and same truck) the AutoCal thinks that I'm trying to program another truck. Not the one that I originally paid for.

Can you please help me out here? I can get you my AutoCal code, if needed.

I look forward to hearing back from you!
