    Your gonna have a great tune when done, been keeping up with this thread and the tunes

    Looked like your MAF only had the lean issue at idle? The extra ~10% increase everywhere else was matched by the BEN factor showing 10% rich everywhere.
    Just need the final dial ins and smoothing now

    Here you go - this one is back in closed loop so you can drive it when you get the rear straightened out. After you get it fixed, log it again - add LTFTs to the PIDs so we can see how they look. We may need to do some more fine tuning, but it is pretty close now. Good luck with everything until you can get back on here!

    im using the 5wire truck maf unmodified

    as for the pluming its not a simple answer.... im running a slp dual air box system. they offered it for the tpi f-bodies back in the late 80's early 90's and was used on the firehawks in 92 I took the tube that runs to both air boxes and made a copy and then modified the copy to allow the MAF a correct way to bolt to the tube with a seal.
