    An ECU upgrade is not necessary, however you will need to add fuel, either larger injectors or RRFPR.

    Ok sweet so I wanted to upgrade the charger what upgrade would be best and how big of injectors will stock ECU hold? I'm new at the whole upgrading ski thing but of course with speed you always want more!

    id run 48s to be safe as per arts recommendation on Ets website.. your boat will come alive with the et 137 and 42s .. its a drop in wheel for the 08+ rxpx skis...

    you can use 42s but a rrfpr will need to be used to adjust pressure.... art recomends 48s for the use of that charger
