i got efi live tunes years ago on my truck from a tuner that is no longer. how to i get my stock file put back on so i can start tuning my self with hp tuners ? thank you justin

Do you have the EFI live hardware and stock file at all? if not you can try to plug in the hp tuner hardware and try to download the tune, if you get e36 or x36 code or it just won't read it you will need to find a tuner that can unlock and/or reset the ECU. I was lucky to have a guy not far from me that was able to help me with this today, but in the USA I'm not sure who does this. i asked on the forum and found a lot of super helpful people there. this wasn't an expensive thing to have unlocked just a 4 day turn around time as it was a days freight each way

Regards Ross

i have five or six files on my laptop due to changes to the truck over the course of sevral years so not sure if one of them is the stock file. my tunner has been shut down so i cant reach out to them.
