You need to give a little more info like what Injectors your using? (Size) some specs of your turbo

I have a t3 t4 turbo I have a safc I'm using a vortech fmu. A inline walboro 255 pump but I have stock injectors and no adjustable fuel regulator. I'm not sure if that's the problem or maybe if I have the fmu setup wrong. Cus it runs lean in boost.

You prob maxed out the stock injectors...

id just some 440+ cc injectors and an adjustable FPR

but then of course you will need something to tune with

when i look for injectors what kind do i need to be able to drop in without modification

What size disc do you have in your FMU?

I think its a 12 to 1 sounds like too much but I found it used from a local guy and figured too much better than not enough. Figured the safc I could lean it out if needed but the safc I can max it out and step on it but as I climb rpm it leans out.

I need to just come up with the money get someinjectors and toss this fmu and get me two of thos adjustable top regulators I guess cus this car has two regulators I've noticed one on the feed line and one oreturn line

One of them is a damper and the other a regulator.

So when ur hooking up the fmu u use the return line correct and. That one is where the fuel regulator is I'm guessing. Or is the regulator the one with. The fuel coming in

I just googled it thanks for the info. I see now how it works.
