    JMO one that is tune-able is best, if you don't have a local tuner
    that complicates it a bit, check with Fuelmoto.com about a powercommander
    they are easy to install, and they will pre-load the tuner with a map
    based on your build.

    It still has a plug in ignition module, on my 00 Heritage its under the seat
    two big plugs.

    I ran the SNS IST with knock sensor on my 124, granted it's expensive but
    a 124 needs a good unit and the SNS is self taught, meaning no dyno needed.

    Daytona Twin Tech has a plug in module that requires some dyno fiddling
    and if you don't know what to do, then you need to get it setup correctly and they will help you

    Fuel Moto - note they will download the map for you and if its off, they will tweak it at no charge, for plug and play with support a good option.

    That's alot of compression to run a 551 .the intake closes at 19 deg .with a static compression ratio of 10.1 the ccp must be over 215 psi .if you get a tc 88 froM dtt. Set advance 1 and slope at 2 see how she runs don't lig it it will ping .
