    X charger without external ic just needs the 42's and your good.

    X charger with external ic needs the 42's and a RRFPR to add some fuel on top.

    I think my AFR's with out the RRFPR where @ 12.4-12.5 WOT

    I'm running the x charger with 42lbs injectors and a 4 inch intake. You'll also need a 14/19 or 15/20 prop. 14/19 will net the best speed but if you mod anymore you'll need the 15/20.
