Got a hold of a Vortech V1. Fmu or upgrade fuel system?

fuel pressure regulator necessary or is that in the tune ?
You will need to upgrade the engine internals long before concerning yourself about an upgraded/aftermarket FPR. The upgraded injectors, fuel pump and tune will take care of any fuel related issues when it comes to boosting these motors. You could always over-build your fuel system for later on down the road when the boost bug bites and you want more power though.
Good advice so far. Could put 60lbers in also. 255lph is fine. Don't **** around with FMU
It's not necessary but wouldn't hurt if you put one on. I'm running the stock regulator on my Vortech setup.
42lb injectors and a strong in-tank pump will take you well beyond the stock shortblock limits. I ran an Aeromotive FPR that fit the stock fuel rail back when I was on the stock system. My tuner said it made tuning a breeze compared to an fmu set-up.
Good to know that i don't have to mess with the FMU when i put mine on... 42lb injectors, fuel pump and an aeromotive adjustable FPR will hopefully make it easy!!
I'll be running a V1 kit as well..

The stock FPR is just fine with a stock shortblock. You're essentially wasting money considering its not as beneficial until you build the shortblock in order to produce more power thus requiring more fuel/fuel adjustment. Put that money towards building an intercooler setup for the centri, spend on an aftercooler and/or methanol setup. IATs can get pretty high, especially with the heat/humidity during the summer time, and detonation on stock motors is detrimental to their longevity. A blown motor makes a shiny upgraded FPR useless, IMHO.
But if you already have it, then why not.

I think I picked it up for $25 a few years ago. It's been sitting in my box of things to put on when I put my blower on... I definitely need to look into doing an intercooler setup.
Thank you everyone for pointing me in the right direction

its getting close to my appt date for the install and i still haven't decided on the fuel system and injectors. someone suggested 60s and a walbro 450 with E85 capabilities just incase for the future. what do you think?
I would NOT use 42's.. Old technology. Junk Injectors that aren't even made anymore..
Deka 60's or 80's.
Aeromotive or Walbro 340 lph intank.
I use 80's on everything.. Will never need to buy another set of injectors, regardless of fuel or upgrades. Idles like stock.
Good day!
I think all the information I have read is good advice, however I wished I had talked to the man who tuned my car after I got everything installed. if you can speak with tuner before hand would be good.
Thank you all for the good advice. I went with 60lbs seimens deka injectors and an aeromotive 340. All new stuff too.
