Message: [QUOTE="Powerstroke Cowboy, post: 899170, member: 610"] Mine smokes like that to. But has gotten better with tuning. I still have a felling Hybrids with 200% nozzles will be harder to control the first start smoke. Due to a couple things. First In order To get a smooth Idles you need to lower the ICP pressure. That in turn lowers the pressure the fuel is injected at. Then with a hybrid you also have a lower injection ratio. 7:1 AA code 6:1 B-Code 5:1 Hybrid. So with a AA code you can have a nice smooth idle @ 750 ICP that comes out to 5250 injection pressure. now to get the same Idle from the 200% nozzle hybrid you need to pull ICP back to 500 or 450 if you want to be a little smoother. With 500 PSI ICP with a hybrid you have only 2500 PSI injection pressure. Less then HALF of what the AA code is . That is IF you are going by Idle quality and sound. Even if the AA code is set to idle @ 500 ICP it still has a injection pressure of 3500 that is still 1000 PSI more. I feel this does play a part in the smoke we see. BUT is not full responsible for it. Like the others have said timing can play a part in that to. I just cant stand the burn my eyes and throat feel when its like that. Need to keep working on it!
