I have a 2008 silverado 5.3 that im tuning using the 2.22 suite, the tune is just about where I want it I have a hybrid tune set up since I cant get it to idle on maf only ive tried everything (any pointers here would help here too). I am using the ve table for startup since it is stock, and then swap over to maf when it gets to operating temperatures I have the rpms set for enable 1200 and disable 1100 on dynamic. The problem im having is first cold start up, it starts up and runs for about three seconds then dies. I can restart it right after than and no problems at all, runs fine..... the only solution ive found in searching so far is I need to use the new 2.23 system, or start over with each change and find out what exactly causes this issue. Any help before I start over would be greatly appreciated
