    I run it up to just under the rev limiter. The stock tach is to slow so not sure what that really is, but I know the sound.

    Cool Top end

    Is there a governor or speed limiter in addition to the rev limiter or are they one in the same?

    Im not positive about yours, but on my 04 GTO there were both.
    I have my shift points set at 6,400 1-2, 6,400 2-3, and 6,300 3-4 on my A4 with no torque managment

    The past 2 times I went to the track, I only spun the engine to 5500 for shifts. My best time so far is a 13.71 @ 104 with a 2.3 60'. Would spinning to 6000 net anything quicker, given it was another 2.3 60'?

    yes, aim for shifting at 6 so that you don't fall out of your power band

    If you have stock springs, that's valve float territory and way past where you are making power. You have to be very careful, valve floating at that point can put one against a piston.

    what would you drop them back down to? 6,100?
