    running rough after adding 42s

    I just added my XS IC and 42's from an X ski today. I noticed that running on the hose afterwards it seems the ski is running really rough. Even my pump was making all kinds of rattle from the vibrations. The rpms used to be very steady but now it is all over the place from 1600-1900. Is this normal do to being rich at idle? It is really responsive and was smooth under throttle.

    Might need a RRFPR.

    I believe with the external IC, changed out SC and the 42's - I am pretty sure you need to put a pressure regulator on there.

    You should be fine with the stock injectors if you have'nt upgraded the sc.

    If thats the case, then he needs to look for a vacuum/ boost leak.

    Thats, what I was thinking, if you look at my modded boats, the exhaust outlet is nice and sooty/lack from being so rich/fat on the bottom. Take it out and run it, thats really the only way.

    +1 It should smooth out some once warmed up.
