    Do I need to monitor AFR with this setup?

    I am thinking of doing these mods to my 2011 RXPX- R&d grate, 4" Fizzle intake, Riva free flow exhaust, 15/22 Solas, Pump wedge. Can I just put these on and go, or do I need to monitor AFR and/or install RRFPR? Thanks in advance.

    should be good to go.
    without adding power you dont need any fuel regulator as long as you are using OEM ecu.

    Thanks guys. I was pretty sure I'd be ok but I wanted to double check. I take it the computer will adjust for the added air intake and exhaust?

    yes. the 215 models can handle around 3 psi of boost over stock before needing anything other than an injector upgrade to 42s. i'm not sure what that translates to for the 255, but basically unless you bump up the supercharger or change the ECU you will not need to worry about fueling.
