if you are under the 4.7 volts you are safe. if you go over the 4.7 volts the car will not run right. you are letting in too much air

You use a multi-meter to check the TPS voltage untill it's AAAAAAlmost at 4.7 volts, then you stop grinding the bumpstop.
Most cars won't feel a difference, but some cars came really fubar'd, and only opening like 85%.

If you go over 90 degrees arent you just back where you started. If you just stick an adjustable screw in youll be ok right, or will the light stay on.
