    Noob question about maf

    Please forgive me for a noob question. I am not a tuner by trying to complete a build. LM7 with 4l60e using LS1 intake. No power adders just small cam and bolt ons. The ecm I have has a base tune and set up for speed density. Going to order a BP harness and it has MAF options for LS1 5 pin or LS3 5 pin card style or speed density.

    1: For a basic setup like mine would SD or Maf be better? Is one easier or more reliable to tune than the other?
    2: Can I run the LS3 card without any tuning problems?

    Asking this cause I want a simple clean air intake but don't want to buy the wrong stuff and when its time to get tuned I find out.

    Thanks for any input. We do not have any local tuners around here to ask.

    Speed density is pretty simple to tune, I'd have no problems doing that. You just have to wire in a IAT sensor into the intake.

    A speed density operating system is offered on just about all the early P01 computers, so that could be applied to make speed density more usable.
    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.
