Well I have the pilot even off completely and something i have noticed is that when engine is cold, say at the start of your day, start up is rough with lots of white smoke, then given about 60 seconds or so it clears up and runs perfectly fine. When engine is warmed up to operating temp or close it starts fine.

Seems like timing is in need of adjustment. This occurs with nothing else modified or whether tuning has had a few other modifications. Cant be too hard of an adjustment.

Truck drives out great otherwise its just when cold cranking then it finally levels out. I was thinking of increasing timing but not sure how to go about it .

Need some clues!! Thanks in advance!

PS... Even before i had efi live , when cold i would notice a slight puff of white smoke. This just seems more exagerated version of that. I always thought of a stuck injector.
