Another quick update:
Ive just been doing some finishing touches on the truck as I go, I work on it a little almost every day. I had to put new upper and lower balljoints on the truck last week, not surprising with 195k miles on the truck. I think its needing wheel bearings too though, no big deal, thats easy enough. I readjusted my valves yesterday, I had a good oil leak coming out the back of the engine too, I thought the rear main didnt seal. Turns out that one of the times I pulled the valve cover off the gasket didnt seat right and go bent on the back of the engine. I fixed that and no more oil leak. The hot IC pipe had a couple small holes in the welds so I pulled that off and welded those closed. Just small things like that.
Ive also been spending a lot more time tuning the pump. I adjusted my preboost or "smoke screw" back to the point that its almost smoke free driving around town. The only downside is that since I pulled a lot of fuel out in doing so, its laggy til 10psi but it doesnt take too long to get there. I also cant spool it up by brake torquing it quickly at all but thats a simple adjustment of a screw.
I also adjusted the starwheel some more so its waits til closer to 50psi to full fuel. I moved the fuel plate to about the middle as well about two weeks ago. This made it so that once I hit 10psi and the turbo lit it would leave a decent cloud if I lay into but then clear up immediately all the way to 45psi.
The only issue was that it was really lacking at the top end, it had good power there, but between 3/4-full throttle didnt feel any different. After doing more research I saw that a lot of people who spend time properly tuning an AFC really have no use for a fuel plate except to restrict full fueling. So yesterday I decided to pull the fuel plate out and see what happens. I took it out for a drive and acted the same as before to 3/4 throttle so obviously a fuel plate isnt necessary any more in that aspect. Then I layed into it full throttle and WOW there was where the fuel plate was screwing me over.
It immediately smacked 55-57 psi of boost and pulled hard. The only problem was it really full fueled then, it went from the turbo cleaning up the smoke to the exact opposite, its just thick smoke at full fuel. It also pegged the pyro so I had to let out.
My only complaint with the truck still is my crusing egts. Going 60-70 MPH it sits between 900-1000 degrees no matter what I change on the pump. The only thing I havent changed is timing yet, I dunno if that might take care of the issue or not.
I think today though Im going to cut the plate to a 0 and put it full forward to restrict full fueling some. Then maybe try a governor spring or something stiffer for an AFC spring to help restrict full fuel and I can adjust tension with starwheel accordingly. I have the AFC set full forward as well, I tried it back halfway and it had zero power on the low end.
