    EFI source sells a 3 bar MAP.

    Or people run the LS9/ZR1/ZL1/CTSV 3 bar map sensor. Though I believe you have to just swap two pins around on the connector for that one.

    I thought these don't support 3 bar?

    They do.

    The MAP sensor you run really doesn't matter, so long as the MAP sensor data is correct. You could run a 2 bar MAP sensor on a 3 bar OS or the 3 bar MAP sensor on a 2 bar OS.

    Even if your computers OS upgrades only support 2 bar OS's, using the 3 bar sensor is just fine. Then you just have to deal with the fueling table being limited to 14psi but you could still log higher with the 3 bar sensor.
