The scanner is asking for a license? Or the editor? I can hook up to any vehicle I want without it asking to license anything using the VCM...

I copied a 99 2500hd 6.0 stock tune over and it was all most the same as running on the stock 4.8 tune and wouldnt stay running. Thats why i copied...

What does force the shift schedule mean?

Yeah they can be pretty subtle and still cause annoying issues.

The cam retainer plate could have a bad seal too, if that is an issue oil pressure will be lower than usual or none at all.

All the stuff on this engine is brand new. The oil filter has been a Mobil 1 , AD delco filters and a K&N Filter no change with the filters. I have...

No. Not the info I was really hoping for or looking for

Break down your swap for us. What did you do and what parts did you use? It went from a 4.8 to a 6.0 but what did you keep or not keep from the...

To spoolboy's comment did you get the injector data and properly scale them?
