The last person I knew who ran 2 tuners ended up throwing himself so far off 
in the end that it wasn't hardly getting a signal out at all. You don't want 
to run 2. Good point on the screw driver though I know a lot of people who 
run a tuner with the screw drivers, some of them, to touch them up a little 
here and there.
