    1998 Fbody 2bar SD

    What GM part # sensor should I be using for a 1998 2bar SD tune?

    Thanks

    A cobalt SS map sensor works, I don't have a part number.

    Or you can buy a 3 bar EFI source MAP sensor that is plug and play for your LS1 harness. You can use a 3 bar MAP on a 2 BAR tune file if you wish. So long as the settings are correct for the MAP sensor, the computer won't care.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
