Hey guys, new to the site and really need some input. I have an 02 7.3 PSD. For about 6 months now I've been have intermittent power loss that mainly happens when climbing hills or accelerating. It cruises fine on flat roads usually but when the power cuts out it falls on its face. It idles fine. I've replaced 3 injectors, VC gaskets, UVCH, IDM, IPR, ICP, CPS, and blue spring upgrade(All Motorcraft/international parts from Riffraff) Also 50 cent mod. I did a EBPV delete, installed bellowed up pipes, new exhaust, and a PHP Hydra chip. Scanning it with my AE isn't giving me any concerning codes and no CEL. Buzz test and C.C test both passed. Im stumped now and tired of throwing money at it. I havent checked fuel pressure or checked the in tank screens. I think that's my next step. Any input is appreciated!
