    All right...so I’ve driven 10 miles out and back through town and on the interstate.

    The 91 Tune seems very promising!! Truck in town and up to 2,000 rpm seems more efficient and that feeling is reflected in my scangauge

    But...get up to 2,900rpm and stomp it and HOLY CRAP!!!! The truck really accelerated up to redline! Definitely can feel it in the seat of the pants! I have a heavy bed cap and tools and it definitely is faster getting to 6,500rpm.

    On the interstate cruising at 68mph there is no where near the hesitation when flooring it to get to 80 to pass another vehicle. Definitely reminds me of driving my 2010 4Runner and how quick that was...this truck now has some quickness to it!

    I’m most interested in seeing the total miles per tank after applying this tune. That’ll take several tanks and tweaking the scangauge but I definitely feel waiting from June 14, 2017 when @OVTune first created this thread to today Feb 10, the wait was worth it!!

    Very interested in reading others reactions as well!

    Good Work Mat!!!!!

    Edit: I meant to say RedLine at 5,500rpm above.

    This does sound promising. Might do this over the Ucon if there are positive SC'd reports. Need some reports from folks with the TRD tune on their supercharged trucks.

    Why wait on tweaking the scangauge? Why not just hand-calculate each tank, to know your immediate results?
    Obviously tweak the scangauge to your desire, but hand calc is always the most accurate.

    Other than that, stoked to hear that you're noticing a big difference!

    If the scangauge is like my ultragauge, after a couple tanks on the tune it is pretty damn accurate. I still calibrate it every fuel up and use fuelly, but it’s cool to know a rough idea where you’re at before fillups.

    Curious on what the dyno numbers were like for the NA tune.

    Yeah, I totally get it. I was just saying that he doesn't need to wait a few tanks to know results, via scan gauge, if he's doing it by hand on the preceding fill-ups.

    So that is something he has to do in the tune, or is it a feature for the end user in the tuner?

    Can you turn off the speed limiter? Adjust for tire size?

    Stock peak limit is 6100, NA tuned peak 6400, shift engage 5900 (stock 5500). The stock ecu is already mapped to 6400 Toyota just cut it short.
    This is done on several of their cars actually.

    300 rpm is nothing. Stock limit on 2GRFSE is 6500 I've revved it stock bottom end to 7600, for example.
