Just got the truck back up and rolling now i notice i ran it up town shut it off. started back up and the thing was running rough wouldnt build anything over 6 lbs of boost. than i let off and back on and i got fuel this time yet still ragged. The whole truck would shake if held on the brake and throttle at the same time. But seemed to go away when i left off the throttle and let the truck cruise and than roll back into it. Now you think its a lack of fuel or stuck injector. No smoke signs. I know its not fuel filter. my injectors are getting weaker. Truck always starts good. I do not have a v2 in my possesion otherwise i would log the rail pressures and injectors. Also it idled fine when this was happening just when id hit the throttle she would dog out. Now i got a lbz danville pump sitting on the shelf. a LB7 reg will work with out any changes correct? i know its a long damn story but im trying to make it clear without having any logs.

Huckstorf is pretty far south of you, but like previously mentioned. Need to take a peak at what the engine is doing.
