Today I was gonna try to get my stock tune of my truck for the first time, after trying it for a few times it didnt wanna work giving me the $0311 code, after doing some research I found out that the Smarty leaves a footprint behind after setting it back to stock. So I read some more long story short, I uploaded a stock tune from one of my other trucks that worked fine and full flashed this tune into the truck that I was having problems with, Then I read on the web you can change to vin# to match with the truck, after numerous tries its a big no no, as soon I try to upload the new vin its giving me the $80 code, and truck wont start.

What can I do here to fix this problem Thanks in advance!
