ElecTech is right on target. If I read your post correctly, please feel free to correct me. Anytime you change the size of the meter or the tube size that's inside, the velocity at which the air enters goes up & down. With only having a 0-5 volt range in the tables really squeezes the algorithms. Thus really screwing with the accuracy of what's it's measuring. Too bad the tables are not based on a 0-10 volt scale. It would leave more room really dialing in your tune. Not being a tuner, I'm not familiar with if there's any adjustability to the proportional gain in the tables.
I hope this helps. If not then just tell me that I'm full of it.
