    So is there any advantage to this unit then?

    Also noticed they are on EBAY for 190 shipped.. I suspect this is what we should all be recommending now for people needing basic AFR systems.

    you can change the sampling rate on the lm and lc 1 ...if you slow it down ..the guage will read more steady...but less accurate..instantly ..sometimes it is changing so fast you cant even really tell what it is..

    and i think the guage looks like crap...
    but it is more cost effective..

    @ what psi # of boost is considered high boost compared to low boost ? ?

    I open more then 40 engines every year, and the pistons on a 12.8 AFR setup that have been racing in offshore for long time WOT are absolute perfekt, no melting no deto.

    But you also need the perfekt EGT value.

    @abi lah, why you want to compare AFR settings if your stock hull RXP-X is running 96 mph, with a GT28

    As Jerry posted, AFR is not a option , there is only 1 AFR that is save an makes power.

    Idle - 13
    off idle to 6000rpm - 13.5-14
    boost 12.8-13
    WOT - 12.5-12.8
    WOT 15psi plus -12.2-12.5

    this is what I tune for
