truck runs fine at idle but when put it in gear loads up bad and kind of lopes.doesnt seem to want to make boost.rail pressure is ok at idle and no blow by in the oil fill cap.gonna get to the turbo today and look it over well and check intercooler. any ideas were else to look....

 

Are you running excessive timing?

 

nope timings pulled back on the c5 the truck was running all out and doing well and it started to loose rpm so i let off,at idle all seems well in gear it jumps an lopes

 

How does the truck run with out the C5?Just stock programing.

 

havnt unhooked it yet but with it turned off no different,turbo wheel is hitting housing,so thats done and there may be a trace of white smoke at start upso perhaps an inject or a ring,newparts will be ordered monday and the off to the mechanic....
