Hey everyone, ive been a member for a little while but never posted because all the info i have needed was in the stickys. This one isnt so here i am.

truck used to smoke like a freight train with the turbo spooled, now it only smokes with turbo not spooled. ive replaced fuel filter, checked fuel psi like 20 at idle and lowest ive got it to drop raw doggin it is 10 psi. ive cracked each of the injector lines and rpms drop like they should, took afc top off and the fuel pin is moving like it should. Any suggestions of what to look for now? Im lost

Sounds like it's running how it should. Black smoke=unburned fuel. Have you lost any boost? If not then you are probably fueling the same as before.

 

It has a small miss to it when its above idle. Boost I havent really lost much maybe 1-2 lbs but it used to snap right to 30 or so. Now it doesnt boost as fast it seems. And it used to black out the road behind it. Now there is just a light haze. Idk how it goes from an extreme amount of smoke to a light haze in the 6 month period I've had the other turbo on

 

valves adjusted?

 

Haven't checked them. Is this something I should go ahead and check?
