    am i running right?

    hey guys new to this forum but am on the riva forums. in my signature you can see what i have and how im performing, does this sound right? i dont think it is after reading some post that with 05 and 06 gprs you can get a pide plate and hit 70. im only hitting 68(rounded up from 67.7) my ride plate is unmodded but still i think i should be hitting higher. thanks in advanced. my best guess is i dont have my efi set up right. could this be?

    Welcome to the Forum.

    There is alot of experience and help here for the GPR.

    In your referral of the ride plate, I would have it modded by Jim's Performance

    Check this thread out, John Abbott hit on some very important things to do.

    there is part of it (i am emphasizing PART of it)--- try these 2:

    Try 6-6-1-9

    also try 6-6-2-9

    Gps the difference between what you have now and each one of the new settings. Glad you have a tach on the way - its the best tool to have when doing comparisions. A tach paints a picture worth a 1000 words about what's going on inside your boat.

    Your pump shoe could very well be hanging down. Do some research on the pump shoe. It needs to be recessed up in there or it, and the grate will hang down too far.
