Hi, looking for help with a first time setup.
2008 Chev Silverado 5.3l flex fuel vin code 3 DOD
engine is freshly rebuilt with a LS9 camshaft, matching springs retainers etc.
dod has been deleted with BTR kit
LSA CTSV injectors
single 67mm turbocharger
2 bar map part #12615136 superseded to GM#19418810
cats deleted and only running primary factory O2 sensors
factory e38 ECM
Factory MAF on inlet to Turbocharger
i started the truck up with the stock tune and engine ran. Cycled engine through a heat cycle and verified engine runs up to operating temp no issues other than throttle was lazy.
downloaded OE tune and performed OS upgrade/patch to 2 bar sensor. Also turned of DOD. Now engine will start and attempt to run but will stall out. will not stay running.
I noticed that KOEO that the Map sensor is reading 174kPa
My tuner guy is unavailable until late march who is going to help me with the tune. But i would like to at least get it running or even start on the tune so that I can move it around the shop.
is there something simple i am missing.
Any help would be greatly appreciated
