Has anyone tested their turbo AFM?

So I tested my turbo AFM according to the FSM and I got the following results:
test #1 yielded my AFM resistance is somewhere around 210-230ohms but a good 40-50ohms away from the recommended 280-400ohms.

test #2 sliding the air flap while measuring the resistance yielded a very shaky needle* as i slowly pushed in the flap and slowly let off. Did it do this for anyone else?

*The exact "shaky needle" measurements are as follows:
when the contact touches the carbon strip the resistance immediately jumps to 100ohms
when the contact goes to the first "carbon strip exit" (doesn't it look like a fwy exit?) the resistance rises to 200ohms and falls down to 400 as it progresses to the next exit.
when the contact goes to the second "carbon strip exit" the resistance rises to 200ohms and falls down to 400 as it progresses to the next exit, and so on and so forth until the flap hits halfway and then mildly imitates the stated function pattern with slightly higher and higher resistance measurements.

I wonder if the "shaky" part is that huge dead spot I feel when I press the throttle down.

Both turbo Z's I've had with an AFM have kinda sucked at low to mid rpm.
