need help truck wont start after installing gorilla tune need help tried installing stock tune back in still will not start

What is a gorilla tune?

What product are you using? If you are using AutoCal, please contact your tuner; for further assistance EFILive would need to know what software and firmware was the tune file written in, and what software/firmware are you attempting to flash with?

Cheers
