After running a smoke tune as a base on my buddies 04 LB7 he wanted less smoke from his truck so I have tried running multiple base tunes and have tried cleaning them up but nothing seems to help to much. We put his stock tune back on the truck and it still smokes quite a bit. About 2,000 miles ago I did a head gasket job for him and in the process found that the injectors were 1/2 to 3/4 cloged up with grit and trash. After everything was put back together and cleaned I did notice a little more injector noise but the truck still runs very strong it just looks kind of junkie going down the road at 1/4 throttle spitting smoke out. I am not sure if the problem lies within the injectors or just the tuning? I am just starting off with EFI Live and know the basics of it but i know that there is no reason for the truck to be smoking on a stock and economy tune. Any help and comments would be very appretiated.
