    Go out and open your TB all the way up by hand and you'll see how the bump stop keeps the blade from opening 90 degrees. What you're doing is grinding off a little material on the stop to let the blade open all the way. Be careful not to grind off to much and if you don't have a scanner to view your tps I wouldn't even attempt it.

    Doesn't it give a certain voltage? You should be able to use a DMM, right?

    Yes but you must know the max voltage otherwise you set a code.

    I'm sure a 90 degree opening will set a code.

    You can approximate the voltage by using this formula;
    Degrees multiplied by 5...example 83.6 degrees; .836 X 5 = 4.18 volts

    For some odd reason 4.2 volts sounds right.......been a long time since I messed with one

    if i was you i would just get a ported polish TB with the bump stop with it for like 100-130 if you dont think you can tackle properly. its cheap and pretty effeient.

    but if you can port/polish your self you can save some cheese, but ill leave it up to the pros
