    None of us are using EGT's. We are all using an air fuel gauge for the tuning.

    I would like to get the EGT sesors in the near future though.

    Do you have any pics of how you modified your exhaust manifold to accept the sensors?

    EGT numbers vary from ski to ski (even the same brand)

    It depends were you put them in the ex pipe and how far you place the sensor inÖ the numbers donít mater as much as they should all be the same. Thatís were you can trim the fuel to even them.

    My show about 1400 F on last chart of the data recorder. (i try to keep them under 1500 F with my set-up

    Its nice to now EGTS because although youíre A/F may show OK, you donít know if the cylinders are equal

    I've been running 760C (1) 753C (2) 738C (3) I'M not sure how to convert this or if the ecm can do it. BUT, last week I burned the baffle out of the water box. It's close to being too hot. A/F was 12.1

    Sounds like your boost is right where mines at at those RPM's.

    Conversion is:

    1567/1508/1533
