    Rev boxes without timing advancement?

    I really need a rev limiter that will bump the rpms but not increase the timing.

    I know of the dyna FS, but I'm looking for more of a 100-175$ price range.

    Anyone know of any?

    i hear the tc and even the big gun is decent. i don't know if either adjust timing or not. i don't think the big gun does but i don't know about the tc. i know the gt thunder is supposed to be a good box but it advances timing 6 degrees

    $99 at www.profabatv.com. Retains stock ignition curve. It is a modified stock box, so they may want your old one as a core (I'm not positive on that, you should give them a call or e-mail). The good thing about the modified stock box is that it doesn't have the anti-kickback circuit, so you should have no starting problems, even if your battery isn't 100% fresh off the charger.

    Downfall with most of the stock modified ones is that they have NO rev limiter at all. You may not want that.
    Mods: Big Gun FS w/MM quiet core, no lid , K&N, FCR41, 11.3:1 440 and Web 479 cam, porting, no choke. Works TRS fronts & Ultracross rear shock, a few other goodies

    The TC does not advance the timing and is the best rev box around in my opinion for the 400...
