I have a problem with reading the 2009 sierra's.
I get a error message, on all of the trucks 2009 and newer.
This is bad for me because the customers are going to another workshop who has EFI live and they tune there, I am losing customers.
How do i fix this?
I noticed it reads the car as a 2000 model??? its a 2009.
Need a solution for this...
