Normal AFM Percentage Readings?
 

What is a "normal" range of AFM percentage readings when running the monitor on the SFACII?

I am only seeing a range of 2% to maybe a max of 60% at full throttle.
Is this normal?

The car has a problem making power when hot. Runs great when cold.
I don't think that this is an install or wiring problem as the car ran great for the first 15K miles that I have owned it and the problem comes and goes so I suspect that the AFM may be failing.

Background -
The car is a S5 NA vert with a paxton super charger.
The SFACII was installed and tuned on a dyno by a knowledgeable shop for the guy I bought the car from. I recently had to replace the TPS and adjusted it per specs. The problem existed before I made this change.

The TPS reading on the SFACII is wired to the wide range pot on the TPS.
