    Installing and using RRFPR

    I'm going to install an etech charger wheel and 48 injectors in my 08 P-X.
    How do I install an RRFPR and then how do I use it? Is it a set and forget it? I have a 4" intake and run in the cool most of the time and don't want run it lean and hurt the motor.

    You will need an o2 meter so you can know if you are running rich/lean and thats how you will know weather you need to add more fuel or take away fuel.

    Innovate lc1, lm1, or lm2 would be a good start.

    Do yourself and get the Riva RRFPR kit. It's a plug and play kit. No cutting hoses and using clamps, etc. Everything is plug and play with the proper connectors. It also comes pre set at the 60 psi base pressure needed to get you going. You can have a look at it here

    You may also want to consider the Mini Rude upgrade for your X charger. It will out perform the E Tech X charger upgrade and will work perfectly with the 48 lb injectors and RRFPR

    After that with the bosh 48's set the key pressure, engine off at 58 boost line hooked up. It will be rich i know i know but start rich and roll the psi down a pound at a time till you get it dialed in WOT. From there you can watch it during big weather swings but if it warms up you'll justs end up getting rich
