Quoted from monsterbaldy:
Hey folks, I just picked up a GB Pro. It works well, only very slight issue I am having is that the subway eject really pops the ball up more than pushes it out. I lowered the power setting but didn't know if there was a better known tweak. The problem with the power setting is that I want it to get to the left flipper, but to be strong enough to get there it's gonna bounce quite a bit.

Hi, I had the very same issue. There was no rhyme or reason for why it started happening. I could hit the pinball in the air with the left flipper on like power 15.
I didn't want to know what would have happened at max power.
The solution for me...
Cliff over at passionforpinball.com sells a stern diamond kickout protector. He doesn't advertise it with the Ghostbusters package but this little guy, number one, is good to have if you don't have one as it will keep that wooden cutout from rounding out over time, number two, can give you the ability to adjust the height at which the ball sits in the storage facility eject. You install from underneath, and the top, on mine, currently sits a hair below the surface which in turn makes the ball sit a tiny bit higher then it would normally when contacting the wood alone. Seems counter intuitive but it works and you can't complain about results.
Email him, mention he's recently help solve a flying ball out of storage facility eject on GB pro and you too want the stern diamond kickout protector to solve that very problem. If you don't have cliffys anywhere else you may also consider buying those as well... You'll save yourself in shipping (unlike me)
