Ok that's what I thought. That leads to my next question. I'm about to upgrade to fic1000 injectors. What would be involved in putting an adjustable fuel pressure regulator on there?

You would have to build a return fuel system. If you need 1000cc injectors then you are gonna need one anyway as well as more fuel pump. You must be planning on adding allot of boost.

Well I have a 76mm turbo and an inline bosch 044 on a switch. Currently on 7 lbs but it made a descent 396 to the wheels. A lot of kinks to work out. This injector thing is killing me

Jake, I should pick your brain because I think we are kinda doing the same thing and maybe there are a lot of headaches you could save me. Like my evap system, maf, and my injectors. Oh and the throttle body (service traction control, stabilitrak) nightmare. It all seemed like such a great idea many thousands of dollars ago

I used aeromotive boost referenced for the turbo. Nothing special just ran -8 for feed and -6 for return back to the tank

It's on a switch at the moment. So you are correct. What is your thought behind your statement
