ya you'll have to re do your manifold flange and downpipe, or make a adapter for the manifold.. then you can always swap turbo's, kinugawa makes a td04 with the t3 flange (rectangle with 4 holes), thats what i got, buuuut kinugawa aint cheap

Seem to be peaking at 5psi with my exhaust on. The wastegate is disabled and I shorted it all the way.
I can see black smoke come out of my pyrometer hole when I rev it. It's just a hose clamp tightened. Would that cause a lower boost? Acting like a stuck open wastegate.

no probably not, but it doesnt help
turn the fuel up...... slowly
take some pics
did you plug the ends of the wastegate feed to the compessor housing if you have it unhooked?
what about getting the new adapter gaskets sealed up ?

Okay I will do that tomorrow. Yes I'm running my boost gauge right off the snout instead of the wastegate. I should order a gasket for the flange.
There almost seems like a dead spot in the pedal around the halfway point, kinda like acceleration plateaus, then I 3/4 throttle it and it builds boost and accelerates. EGTs are still in the upper 800⁰F-1000⁰F just going up a hill or accelerating quickly, was kinda expecting lower. Cruising is fine but I'm only make 1 pound of boost cruising in 3rd at 60km/h.
I might just be over thinking it, I still have to remember it's a 2lt

Should be same for all VE rotary pumps. A screw in pump cover I think.
Info here: Rotary pump fuel screw - https://forum.ih8mud.com/threads/rotary-pump-fuel-screw.867779/
more fuel should net better turbo response and more psi up to the point your wastegate lets it release, you may need a stronger wastegate or clamping it closed by some means to get more psi, fuel can be turned up until you are hitting 1200f under maximum load ( big hill ) hottest day scenario... being a bit conservative is best. If you are blowing any black or haze under full throttle you probably have gone a bit far, you dont want too much fuel for heat reasons, peak combustion pressures etc.
ive heard you can get to a run away fuel situation on some fuel pumps so be somewhat careful.
that turbo should be able to give you 15psi without even trying
more psi should also help cool your egt's (to a point) intercooler helps here too

you can watch your boost gauge and see where the wastegate is opening, sometimes it kind of 'flutters' a bit on the gauge as it begins opening.
where is your egt gauge located. pre turbo in the exhaust manifold is the only reliable place to monitor it.
you could still have pressure side leaks, including the intake manifold gasket
your wastegate will still be opening even with the sense line unhooked, it will just be manifold pressure opening it instead of manifold pressure+boost pressure on the wastegate diaphragm which is why you should 'clamp' it closed so it cant physically move, then you can see what it will push (psi) with the fuel (exhaust gas) you are sending it, be cautious tho, monitor things until you are confident they are in safe parameters
