If it can't be cleaned up with a tuner, then the electronics are bad/got damaged/are dirty. I have two sets of electronics so I was able to verify that one set was indeed bad. Having used two different diameter tubes (76 & 80mm) and 5 different sample tubes (clear, black, red, blue, and Tuner), S/C & N/A, I can verify that the meters have no inherent issues with being tuned. If the meter has a bend immediately before or after it, then all bets are off - but this is common sense stuff. Here is a post that discusses all this stuff. I love his description of a ProM Bullet meter:

The Bullet is for all intents and purposes is a ****ing fluted exhaust pipe with a molded plastic "sampling tube" with a draw-through slot cut in the back of it shoved into the pipe.

I could point to a dozen folks who have cursed to high heaven using a ProM or PMAS meter, so examples of people who can't or refuse to tune properly or give up after 2 days are a dime a dozen...
