    Well I finally went and got dyno'd.. My mods are an open element air filter, open cutout, and custom PCM tune by Jesse at Wait4Me Performance.

    Heres the results of the 3 runs:

    Run 1: Max Power = 264.45, Max Torque = 300.15
    Run 2: Max Power = 264.89, Max Torque = 301.57
    Run 3: Max Power = 258.65, Max Torque = 305.25

    It was on a Dynojet dyno at Alamo Autosports in Arlington, Texas.

    My next major mods I want include LT headers, as well as a new cam, full intake(vs the ebay intake I have now), underdrive pullies, and E-Fans!

    Cant wait!

    I hate asking stupid ?'s airdeano (see above post) but would that 3200 not creat a handfull of spin on the street? I have a hard time keeping the rearend planted as it is now with the 1600 stocker.

    Aye, at the wheels. I am glad to have a number to work with now lol, previously I was just throwing numbers up and guessing, but now I know what im running and can get re-tested after a few more mods.

    get some "sticker" tires. a better treadwear rating.
    100 or less = liquid rubber stickest
    150-100 = very sticky compound
    300-200 = "semi-stick" traction longer wear
    400-300 = rock hard durometer longer wear than 200
    600-400 = fred flintstone tires no traction, just rollers.

    the action of the driver is to have more power, when the
    converter is "holding" power down, the driver is cheated in
    power output.
    youll notice on a dyno graph, the torque peak (335lb/ft) is 4000rpm
    also, youll notice on a dyno graph, 3200rpm torque is 310lb/ft
    on a 5.3L. having the converter hold torque @ 1600rpm is 250lb/ft.
    http://media.gm.com/us/powertrain/en...L33_Sierra.pdf
    thats 60lb/ft of torque difference. if spinning tires is a
    problem, id fix it, due to the competition can get 3 car
    lengths before you recover.
