    mine made 194 with full bolt ons.


    I'd guess 175auto/180manual.

    but we're close ;) lol.

    Yessir. These cars suck stock.

    159 uncorrect was equal to around ~175rwhp. And that's through an auto.

    It's amazing how far technology has come. A v8 at even 200rwhp factory would be laughable nowadays

    So true. Altimas and hondas come with way more hp than our cars stock, it is a joke.

    In the poor motors defense, she has enough torque to at least make it fun. I don't think a 4 banger altima can put down 250ftlbs

    No I doubt an Altima puts that down. Arguing a V8 mustang vs an Altima is point made though lol

    I'm assuming that's not to the wheel.

    lol so glad I ditched the GT! PI parts and full bolt ons and it still couldn't get out of its own way.
    The numbers look like they've been covered above.

    There is no way a stock NPI with a PI intake and some mufflers made 50rwhp over stock.

    That dyno must have smoking that good stuff.

    ^ word.

    Also, 100 shot on top of 23x whp = 290? Crappy gain for a hundo'.
