Congrats on your new game! A few thoughts:
Quoted from Buzzkill:not sure I have it setup right (perfectly level horizontally, and 6.5 degrees tilt, but still can't make ramp shots easily - guessing that is normal?).
Have you tried adjusting the flipper strength? I don't own an MMR but think I've read this setting is in the diagnostics menu.
Quoted from Buzzkill:wizard hole needs adjusting (pops out most of the time without registering)
You may be on top of this already but this is an issue with the original MM as well, here's one of many threads discussing:
