you take a reading of the middle wire on the tps, and it should be .67 and you will have to slot the tps.

You just take a drill bit and make the holes oval, so it's adjustable. At closed, it should be .54-.67v (mines .56) and at WOT should be over 4v , ideally in the area of 4.2v but 4.5v would be great. (that's what the Casper Electronics TPS voltage modifiers do)

What brand TB did you switch to? Holley throttle bodies have been known to over rotate. I had to make a throttle stop for mine.

Holley TB as indicated will over rotate past WOT.

You want less than 4.8 Volts at WOT>

Take your intake elbow off and open the throttle body blades all the way by hand. See if they go past flat.

Slot, oval, same thing. Here's a pic of how it should look. Mind you, this is a factory adjustable one, but you get the idea.
