(Posted this in wrong section the first time).Okay fellas I need some help with my new (used) toy. I bought a 1992 W250 with a p-pumped 12v. Im having some issues with it. The truck has the following mods done to it. 12v P- pumped,no fuel plate or afc, Hx40 turbo, no waste gate,191 delivery valves, arp head studs, Big front mount IC, 50hp pod injectors, timing at 16*,cold air intake,raptor 150 pump,4inch down pipe to 5 inch stacks, ATS 3 piece manifold, NV 4500 trans with south bend clutch. The truck is hitting 42 psi of boost and 23psi of fuel presure. The problem im having is that it stubles with blue smoke at a low RPM then it smooths out after the RPMs get higher and blue smoke goes away. Fuel presure never drops below 22 at and RPM or throttle postion. Its seems to be down on power but this is my first 12v so im not to sure on how well they respond and perform. Any help would be nice. They orignal owner told me timing needs to be reset for cold wheather but im not so sure.

that sounds like the timing has slipped.

 

Does the smoke go away at temp, or is it there all the time? If its there all the time, I'd look at getting the timing checked.

 

Smoke is still there. Just not as bad when wormed up and the sputter is still there but not as bad when warmed up. Should this truck be a strong runner(first 12v)

 

Just outa curiosity The POD you are running They are for a 1 St gen low pressure Ve Pump ... Has someone reset them ?
