    215 x charger a/f advice

    Hi Guys,

    I have used this site as a resource for quite a while now but this is my first post. i will start by listing my mods then i need some advice on the a/f's and tuning.
    -x charger
    -fizzle intercooler
    -rrfpr (currently set at 61psi static)
    -hks ssqv
    -water box mod
    -flow through exhaust
    -rude fuel controller (being installed this weekend)
    -mtx-l a/f gauge
    -boost gauge
    -riva opas block off
    -riva wedge and vts rod
    -worx intake grate
    -42lb injectors
    -les cook ecu flash limit at 8400
    -titanium valve retainers
    -4 inch intake
    -solas 15/20 prop

    i think that is all but im sure i will have missed a few things..

    anyway, i need to know if this seems 'safe' in terms of boost and fuel delivery, i would rather pre-empt any damage to the engine, i was also wondering what sort of a/f ratios i should be looking for on a setup like this, as i will be tuning this weekend. And if anybody has any advice on the tuning of the rude controller, i have worked with fuel controllers in the past on cars and i have the a/f analog output rigged up into the rude controller to log and help the process..

    i was also a little concerned about when the ski becomes unhooked in the chop, it hits the limiter the blow off goes off and it seems the a/f shows a really lean reading, is this correct?

    any advice would be greatly appreciated as i have gone over this site thousands of times and it seems everything has been done and the outcomes of most things have been experienced!

    thanks

    Not sure.
    What year is your ski?
    Alot of us replace the fuel pumps when needing to flow more fuel then stock.

    It's an 05..
    I have read in places they are good for 80psi which seems high, I am more concerned about when the ski unhooks, cause the revs are so high but I guess the boost is released.. Just don't want to lean the thing out and cook it! I did it to a project car once and I promised never again!!
