    LS1 TVS2300,AI 317 heads, cam

    Wondering if you fellas could help me get a couple questions answered about my project that I am going to take a wack at tuning.
    To start the engine is a 99 LS1/T56 in a 69 Camaro. I installed a Magnuson tvs2300 and AI 317 heads with cam on it. During the install I also installed a 2 bar MAP sensor also.

    Initially I was planning on doing a SD tune to the car but wondering if I a MAF tune would work better for my car. Its not a drag car or anything more of weekend cruiser. I want to keep maximum drivability. Will I run out of range for the MAF with my current set-up? or will it just be better to stick with a SD tune?

    Thanks in advance.

    Sounds like a fun project. With a blower, I would SD tune it. You might be ok with the maf depending on where you place it in the intake. SD is just easier to tune and mine runs great anywhere I have driven it.

    SD tune was my original plan. I am not quite at the tuning stage yet, but I am trying to get my ducks in a row for when that comes so I am not blindsided by things.
    The MAF was in the middle of the intake tract when my car was in "stock" form. I have a AEM wideband that I will be installing into the car to help me out when tuning also.

    Sorry for what maybe newbie questions, but I figure a guy has to start at some point.

    Id like to hear some more points on the original post also, maybe from both side of the fence (sd and maf tune) with boost.

    You can drive it anywhere you want and in SD like said above if the tune or right..
    MAF placement is very important (no bends, nice straight path pre and post sensor is key)

    SD or MAF work fine

    As of now the MAF is located in a straight section of the intake tract, probably 6" of straight 4" pipe on either side. If I were to tune it with the MAF, how do you adjust for the 2 bar MAP? I know there is a 1 bar MAF OS...

    Digging it back up finally. Been a minute

    Wondering if anyone had a tune I could reference for a tvs2300, 2bar VE table and 60# Siemens injectors with a boost referenced pressure regulator.

    Finally got the car drivable, and my intent was to fully road tune it myself but I had an opportunity to take it to a local tuner and did it as I was running into somewhat of a deadline.

    The car made 500/480 on a mustang dyno at 6psi. Drivability is really good and do plan on still doing some "fine" tuning as I drive it around.
