    Tuning After Iron Horn Fixed - Vane Installed

    Hi all,

    My VGT bit the dust, and i replaced it with the iron horn S364.5 .91 fixed vane kit.

    My truck is deleted and currently tuned with a Mini Maxx, and I'm running the most recent software before they went under.

    Usually, keep in on-street mode unless I'm towing, then ill use tow.

    It seems to run fine, no smoke unless i stomp on it, but I wonder if the software would benefit from modifying the software to optimize running with the fixed vane.

    I'm not sure if anyone still writes tunes for the Mini Maxx, and I would consider going with an MM3 if there was a definite benefit for the fixed vane.

    I'm keen on reliability, but some more takeoff power, if anything, is what I feel is missing with the fixed vane turbo.

    Thanks all!

    A retune will make a world of difference.

    My S366sxe spooled like a dog until I updated my tunes, and thats with 45% overs.

    Get an MM3 w/ tunes via DRD.

    ETA just realized how old this post was, LOL.

    I hope this helps answer your question.
