My brother picked up a 08 last week, the truck was tuned with an autocal and EFI from someone else.
I was going to update his single efi tune to a CSP file but wanted to make sure I got the correct os in the truck. I read the file that is in there now and the os is a 11551031. According to tune file depot this is for a 07 manual truck, his is a 08 auto.
Should I re-use this same base file to build my CSP file or should I start with the one that is for a 08 Auto?
