Do I need to upgrade the fuel system?

Im running 94.5% on the injector duty (as shown on my PFC)

I know I have to either get it tuned or go with the fuel upgrades....

If you know, What would you guys suggest for fuel upgrades?
as far as
injectors, fuel pump, RRFPR.....???

What should I do? Let me hear your thoughts or what you did.....

I am definately not a tuner but most of the guys I know have had the stock fuel system support up to 300rwhp safely. I run about that with a upgraded pump. This all assumes you have it tuned by a competent tuner. Most of the guys I know running over 350 hp have blown at least one or more motors if they didn't upgrade the fuel system and intercooler sufficiently. Is it possible? Of course but it all comes down to how hard you drive the car, type of gas you use, and about a dozen other factors. I prefer to protect my investment and run it safely. But if you got the money to fix it I guess you can run it right on the ragged edge.
