    My Roush Stage 3 is completely stock. No aftermarket Oil Pump Gears or Crank Sprocket.
    Never heard of any engine failures with a Roush tune. Mostly because they are tuned for longevity and reliability.

    It is.
    I believe it is at set at 6,800RPM.

    Yes, 155MPH on the speed limiter. (My bad. I thought he meant what the engine revs to.)
    155MPH was the speed limit on the 2012-2014 Roush cars as well.

    Mine has always reved to 7,500 but it would cut timing around 6,300. With the phase 2 tune that does not seen to be the case. I have not logged it yet but there's no noticeable drop in power all the way to the redline (like it should be). I actually made my peak power 639WHP at just above 6,100 rpm on the phase 1 tune which is way too low on rpms for these cars. I'm running the MT82 so my #s might be a little higher than others. I think 610-620 ish is what the 10r80s usually dyno at.

    Yeah,...maybe that's what it is then because Ken @ PBD shows that the rev drops at 6,800 on a stock Phase 1 dynograph.
    With his tune, the car revs to 7,500. He said these cars love to high rev.

    Yeah, if you have oil pump gears and crank sprocket most tuners will rev them to 8k or so and they make peak power pretty close to the 8k mark when they are tuned aggressively.

    My Roush setup is phenomenal. 12.5psi @ 7200rpm (72mm pulley). ID 1050X’s, BAP, Kooks LT’s, GT500 twin 60mm T/B, factory resonator and mufflers, and 17.5° of timing(locked maximum) on 93/Torco blend. Through a 6R80. 1E0A9B6A-27F5-49FA-A9DF-8878AAC11FB2.jpeg

    That's pretty awesome Cory. Yours is the 2300 TVS, correct?
    Did Pete in New Hampshire tune your car?

    Nope. He’s not tuning Coyotes anymore. I did use his dyno today though! Yes TVS 2300.

    It’s a 2016 GT. Sorry for not pointing that out.

    Right this is useless, impressive but not an 18

    No offense but we’re talking 18+ cars

    the GT500 on the front page just ran a 9.5 with the toyos so grip shouldn't be an issue. Good luck
