Hello fellow truckers im new to this stuff I have a 04 silverado and I purchased EFI and need some help with it,dont know where to start can some one please give some info.... Thanks A lot...

 

at the top of the Tuning and Diagnostic section there are starter threads to help you out. And if you have a specific question on something search it first then post up. What do you need help with specifically? I have HPT but the programs are somewhat similar. Like i said, post up what you specifically need help with and people will chime in
