    RXP-X 2011 with RUDE 1 and Riva Intake will need something else...injectors, RRFPR?

    Im planning to sell my RUDE 1 and a riva Air 3" intake to a friend.
    He´s RXP-X 2011 is totally STOCK...
    The question is... AFR will be OK with the X-ECU, or he will need 48 injectors or a RRFPR?
    Temp goes from 55F winter to 80F summer open sea...
    Many thanks in advanced

    No one can accurately tell you this. For that you will need an AFR reader on your friend's ski. My guess is that he will need the 48 LB Injectors. Or he can get an RRFPR and add some fuel. Does he want to keep it stock forever or is he going to keep moddong? If so then i'd suggest the RRFPR as an option and definitely get an O2 reader in there.

    48's may be enough. Only way to tell would be to monitor afr's. Its best to monitor them when upgrading sc if nothing else so you can tune it to run best. My 08 PX with Riva sc upgrade (not sure how it compares to a Rude1) stock ecu and 48's I was way rich at wot.

    Would still be the same, you would need an AFR reader in there.

    I wouldn't waist your time putting the Rude 1 on The X boat.....Your not gonna see a whole lot of improvement from an X charger to a Rude 1..IF you want to upgrade the Scer i would go to a Mini Rude upgrade..Youll see alot more performance gains with the Mini Rude than you will with a Rude1..NOW If you want to put the Rude 1 on the 215 HP boat you will definatly see a performance improvement..

    the problem its that im selling the RUDE 1..., i want to upgrade mines and i have a buyer that wants some more power without using a RRFPR...
    I think he would have some more horses with the RUDE 1 and the 3" air intake and 48s..., either than stock..., i figure he would feel som 10-15% improvement in hole shot...

    Not on an X boat..There is not that much difference in boost between a Rude1 and An X Charger at 8100 RPM..Not enough IMO to justify the change...IF anything your looking at a max of 1 PSI of boost if that....And IF you installed a Rude 1 on the X boat you dont need 48s,Youll IMO be way to rich..Even with the 3 inch air intake...

    Yea, not much gain until you spin the motor north of 8500...

    You'll get more out of the X SC if you open the intake up to a 4"...
