R & R this and that to try and find lack of power

Fuel pump went out back this summer and truck has not run right since in stock power setting. Seems to run well and have been driving for months in 80 and 120 settings but seems low on power in 80 tune to a degree. Am replacing all orings on turbo and pedestal , replacing up pipe gaskets as they are leaking , gutting ebpv and pedestal , gonna replace the cps as it is leaking from the oring and i need a spare , gonna rebuild turbo and install a WW. Dont know if any of the seals and turbo rebuild will help but it has quite a bit of shaft play to the point it is close to hitting the housing so figured what the heck. Is there anything else i should do up top while i have all this taken apart ? If this fails to remedy problem where to next ??? injector problem ? HPOP problem ? will dump smoke in 80 and 120 tunes but takes about 45 seconds to go 0-60 in stock even after removing chip. Only codes were a glow plug relay 2,4,6,8 i think it was and a maf i believe it was or map ? Sorry for the long winded post , but wouldnt turn anywhere else with it unless it just goes well beyond my mechanical means

Do you know what your fuel pressure is? If you lost a fuel pump and just threw another one in there you could have an issue with your pick up...

You know i blame you for much of this.( only jokin')...after seeing all the goodies my buddies getting from DI in Houston per your recomendation i have the bug again !! i believe it was a motorcraft fuel pump from dealer though
