    RXP breaking up under boost

    I took my ski out for the first time this year after I added a external IC. It runs fine but every time I make it go into boost it breaks up and falls on its face. I added 42 lb injectors and it made no difference. I have no check engine light. Im out of ideas right now maybe some of you guys might have some. The only thing that bothers me is that I didnt run it this year before I modded it so I dont know if its something I did or if something changed while it sat over the winter.
    Any help will be appreciated

    check your spark plugs first

    check the water lines but you should get a alarm if they are wrong

    I put in 2 sets of new plugs already. The intercooler is a spearco. I have the water lines hooked up correctly

    leaks

    did you spray soapy water on the i/c piping too see if you had leaks


    is the ski bouncing off the limiter

    what is your max rpm?
    what prop?

    tell us your complete setup

    The rpms wont go above 6000 under full throttle but half throttle it will. I have a 14/19 prop, intake grate, 42lb injectors, riva rear exhaust and im running no intake right now. I did not check for boost leaks yet that was my next thing.

    42 lbs

    do you have an aftermarket wheel on the s/c

    if not you are probably way too rich

    what does no intake mean?

    You may have changed plugs, but do you know if your coil packs are ok! They fail under load.
