    Be careful. That charger maybe a little better than a stock X-charger. Just 42's will not be enough. Hopefully some guys will chime in here that have close to your set up.

    I ran that on my 07 RXP. RRPFR set to 58-59psi and 42s for a 11.9 AFR at WOT in the Florida heat.

    Exactly. He didn't mention any RRFPR just 42's. Thanks for the post.

    what about if you put 48 pound injectors? will this be a good setup?

    If I knew dduck's WOT fuel pressure with the 42's, I could tell you. I only have one friend using a stock 07 RXP ecu with ET140R, external IC, RIVA rear air. He is running 50's with a RRFPR. Everyone else has AM ecus.

    I would go with RRFPR and 42s, The 48s on there own may not be enough on there own and will be richer at idle that the 42s. I would monitor AF to get the RRFPR where it needs to be. R88

    i would say go RRFPR with 42s and spend time getting afr where they need to be as oposed to 48s.
    with 48s your going to be far to rich low down and mid range prob leading to it being sloppy and in extreme cases bore wash.
