    Yes, my top speed is set at 225 MPH. I try to keep her below half that tho.

    160+ is pushing it without any suspension help, but it can be done with a tune only.

    Mine has no limit now after the tune, but I imagine you can have it set at whatever speed you like. Try a buck sixty!

    My limit is what it will do in the 1/4 mile. But, to answer your questions, yes you can adjust your top speed limiter with a tune.

    He's right. Thing start to get a little "dicey" much above that. My personal best with an GPS-based recorder was 181 and I do not want to do it again without major suspension and brake work
    Winning may not be everything, but its still better than losing

    I don't know you. I don't know what have done. If you are looking to talk up a race for 3 hours, I can tell you I don't have the time. But what I do have are a very particular set of parts; parts I have acquired over a very long career. Parts that make me a nightmare for people like you. If you go home, that'll be the end of it. I will not look for you, I will not punk you. But if you don't, I will punk you, I will race you, and I will embarrass you.

    Yea mine was also set there. Not sure why some are different, unless the dealer changes it for some insurance reason.154 is fastest I've had mine.
