    XX Charger Question

    If I get a XX charger I see it says a certain boost at 8100. will I still need a aftermarket ecu or can I just use a RRFPR and some 50s?

    No you do not need an aftermarket ecu. At the moment i am running on the stock x ecu with 48's.

    Sure you can run it with stock ecu and RRFPR
    But you will not be able to see all potential of this charger until you reach 8500 rpm

    How drastic are the inertia pull shots and hole shots going from stock Xcharger to this?

    had no chance to try it with stock ecu, but it works great with aftermarket one with 8600 rpm limit

    On a stock 05 ECU you will need to regulate the fuel..You will be pig rich in the lower RPM range with the stock ECU/50s..You can use a RRFPR to help get the upper RPMs dialed in BUT You will also need a Begi or fuel Controller to help down low with your AFRs..

    I have a 4" front intake and 42 pound injectors. My S3 supercharger had a bearing frreeze destroying it. I would like to replace it with the X charger but i don't really want to go to a RRFP
    R or other than my stock ECU. Can I do it? Thanks in advance.

    Yes u can. There is a certain plug you have to run that will allow enough spark to correct the air fuel ratio.... Or so I have read.

    What potential. It says on RIVA's site that the XX makes 13.5 psi at 8100 and 14.5 at 8500. I don't see the potential you speak of. I don't presonally have a Riva ECU on any of my skis but from what Riva says you only get one more psi of boost from upping the RPM's a couple hundred.
