5.3 first attemp at a tune may need some adult supervision
I have taken my 4.3 out of my 2001 Silverado and replaced it with a 5.3 whitch I added a GM stage 2 cam. I used a factory flash for a 2002 that has all the same equipment to get the truck running. I am having an issue with rough idle P0106 and p0121 codes, off idle and WOT seen to be good but still have a raw fuel smell whitch I am thinking my be fixed with injector timing.
cam specs
intake duration 227
exhaust duration 239
lobe separation 108
degrees overlap 17
lift 551
Is any help avalible
