[QUOTE="mandkole, post: 1295000, member: 4630"] When I got into diesels 15 yrs ago, the 7.3 performance stuff was starting to get good. Some were still blowing them up on propane but everyone was learning about injector mods. The DIY injector deal started to become a thing about 10 yrs ago and I tried it,--spent a lot of time on them and two different afternoons in the local diesel injection shop with a flow bench. The shop owner humored me for being the first local guy he knew of who actually tore a set down. He quizzed me on where I got the orings, machined pistons, etc, educated me on properly torqueing the halves together, showed me how the flow bench worked, etc. Like all parts in a heui, its a big deal if you don't know the tricks. The set flowed within 2 ccs (156-158cc) at high rpm/ICP, but could not get them much closer than 1.5 from each other at idle... that's an issue. The set ran a little smoother, but still had basically the same chunky idle prior to the build. My first trucks motor was not well maintained and the oil sides were pretty blown out. That armature gap was tough to get right with no spares, machine tools, etc. What the hell, give em a shot. [/QUOTE]
