    Quick supercharger question

    I have 2012 seadoo gtr 215 with stock supercharger. If I upgrade it with the et 127 wheel and spacer will I need to buy the rising rate fuel kit or would I be able to have jesus @ riva be able to write a new tune and be able to use the stock injectors?

    Stock injectors on a 2012 are 48lb , you will need a tune on the Bosch ecu's to unlock the limiters.

    No need for injectors. Yours are already 48 lb hr. Jesus/MaptunerX already has a perfect tune for that supercharger upgrade. The GreenHulk Store has the ET127 in stock and MaptunerX bundle packages on sale

    Run the 127 wheel, rear air intake otherwise you will experience harmonics on the mana flex with that wheel. Run a 15/19 impeller, retainers and spin it to 8600rpm with 8700rpm limit. You will love it

    also i see some skis have hose claps on the supercharger hose instead of the oetiker clanps. Is it necessary to put those back on or will hoseclamps work?

    A 4” elbow off charger with 4” tune and filter. Use t-bolt clamps
