You need to measure on the purple wire. Should be about 4.70 volts at WOT. It will set an SES light if you go too far.

It should set an SES light then yes it may drive/shift odd.

It will immediately short-shift you if over 4.75V, and at
more than 10 seconds there will set a code. Your bump
stop should be ground for geometric dead center on
the blade, not voltage, and the voltage trued up later
if it's off (but should not be if the mechanical is right).

Ok at the track it acts up, rpm sticks at 5 in 3 rd and power reduced like it starving for fuel.

Would it allow to much air in and make it starve of fuel? I put a stock tb on it and it ran better on the street, now just have have to test at the track.

Why not just measure the voltage to see where you are at?

I understand your line of thinking is the correct way BUT, how is the voltage per angle adjustable? I thought it was set.

I put a stock one on just to make sure it will work ath the track. If this is the prob then im going to just order a larger tb. If this is not the problem all I have left is torque converter or rear end everything else is new or been replaced.

So the idea is to measure the height of the blade @ wot and grind the throttle stop until there is = measurement top to bottom? That seems almost too easy... Something I can prolly handle then!
