    I know the fuel psi harness does not work at idle though on most trucks

    Ive heard it comes wired with a switch now so no more rump rump at idle. its interesting how each engine responds different. 1 friend has 09 550 idles smooth but has high fuel retriction code at times. another with same engine idles a little rough but no codes

    The one's on ebay are a replica from the person that makes them in Alaska. Back in the day my dad went to a shop that carried them from alaska and only some trucks would work with the fps. The ftc would always work. So i don't know why some one on ebay is stating that his works.
    Well i made one for my dad's truck the fps that works in stock mode and more power. Dyno tested in alberta so i know it works. Mine also has a switch but it's built in.
    The rump rump is it de-rating.

    What is the differance of the Diesel freak and Antrims harnesses? the Antrims harness looks like it has some kind of module while the Diesel Freak harness looks like a some wires spliced together ????

    A buddy of mine has the one from Antrim with the on/off switch to keep from having check engine light coming on at idle. I know it was on dyno and can get hp #'s tomorrow if your interested. He has isx 600

    He said he went from 503rwhp to 581rwhp. They tweaked it on dyno to the limit that check engine light didn't come on. Since then, he had egr removed, manifold, turbo and dpf hollowed with the mildest pdi program . He hasn't had it on dyno with those changes, but is content with the way it runs. He still uses the Antrim box because it has switch to try to keep it clean for nj. He feels the power increase the most in top end. Hope the info helps.

    Also he claimed he gained 3/10 mpg but he is sensible driver. Rarely over speed limit and uses power to maintain speed not build speed.
