Quoted from Gogdog:

Manual plunger
Increase power: Setting the manual plunger to hit dead center on the pinball. If it already is...then you would have to switch the spring to a stronger colored spring.
Decrease power: Easy....move the auto plunger so its not quite centered. I would recommend that you keep the left/right alignment and move the plunger vertically to decrease power (if the plunger hits off centered horizontally it might slightly move the ball out of the ball guide in the lane). Its also possible maybe you could add a small washer to the plunger so it doesn't hit the ball quite as hard.
In my example....my manual ball path was lower than the auto (manual hitting post and auto hitting top flipper). So, I left the auto alone and decreased power to my manual. It was enough to get them close to the same path.

Quoted from Kevlar:

New pro owner here, 27 pages is a lot of reading, can someone point me in the right direction to fix balls flying off the left wireform? pretty sure its not reaching the end of the wireform, flying off on one of the bends. Is there a way to slow the ball down?

Quoted from lewislama:

So sick of being punished for making a great right ramp shot only to have the ball fly off the ramp and end up in the trough. Ended up putting three flipper rubbers over ramp where the ball gets air at high speed. Works great. Looks.. so so.[quoted image]
