I have a 2008 GMC Sierra 1500 SLT 6.0L L76 Gen 4 ( Y code )
BRT Stage 3 Cam, Cathedrale Port Head, Holly snipper Intake, 58LBS injectors, full header, 3000 stall, stock bottom end.
I can't get it to start up. I have wrote a tune and the truck will start for 3 seconds and then shut off.
Attached is HPT file, Log File, and Log file vehicle profile. I have read several forms and can't find the answer.
Any help would be appreciated.
