Injection Pulse Width Specs, Short Term Fuel Trim

im looking for some info on the Injection Pulse Width specs for an 08 6.4, mine is reading 0.35-0.57, that i think might be related to my turbo issue, any help on this 4 month fiasco and 4 different dealer nightmare would be greatly appreciated, there only answer so far is to upgrade to a 6.7 !! also any specs for short term fuel trims, mine seem far apart, injector 3 an 6 are 13% apart, thanks

Honestly, with a stft being off that much on opposing cylinders, the first thing I would look for is a leak.. either exhaust manifolds, or valves not seating... An exhaust leak could certainly create turbo pressure issues, too... What does the ltft read? Does the computer think it's balancing out or are the ltft's whacked too?,
