Default 1st gen upgrade help!!!

Im looking to start upgrades for my first gen. I have in mind what i wanna do to 1st i just would like some input since i know there is alot of knowlege on here.

To start off i am one of the lucky ones with the VE pump that is not adjustable. With that being said im looking at starting off with injectors and turbo upgrades instead of a new VE pump.

Im looking at 5X.0012s DAP injectors, a 60mm compressor upgrade for the h1c( currently have 18cm housing) and 3200gsk.

Does anyone see any issues with these upgrades giving my situation with the VE pump?

Default Ve pump

I have turned the power adjustment screw all the way in and no extra fuel is given. I found a couple articles that mention it online. But don't to give much details on it.

Every ve pump is adjustable check out the sticky to understand a little more about the ve pump and understand and thing called run away and be scared of it and have a friend with a 2x6 block of wood there with you once you understand what to do to make sure you dont loose you engine you key switch will NOT save a run away and dont be one of those guys that tunes to have a coal runner tune for power I tuned for power and I can put many cars and trucks to shame and I only push grey at most and im talking running 13 quarter mile times and the first thing most important!!!!! GAUGES a smoky truck is a hot exhaust temp truck so on that note good luck oh and get a 366 gov spring 3200rpm no joke best $20 you will have ever spent

The 366GSK is on the list. The gauges were my first purchase and i just got done installing them. I have done alot of reading on the VE pump and have tried all adjustments. I turned the fuel pin and it helped. as far as adjusting the full power adjustment screw and the star wheel, there is no change in fuel flow or increase of power...if ALL ve pumps are adjustible then perhaps is the something internally wrong with my pump? the truck runs great and is dependable i have zero issues with the pump (besides making the adjustments) i am well aware of the runaway situation and have moved the power screw all the way in "clockwise" and all the way out "counter" so im not sure what the issue may be. Thanks for your help!

Yes. loosen the lock nut with a 13mm wrench. Then adjust the screw in and out. The bolt moves in and out with no issues its not corroded or ceased in any way.

There is a safety lock ring on there too that you have to break off have you taken that off? Its a like a metal sleeve that is wrapped around the full fuel screw
