Use a giant pusher fan to keep the condenser working at a steady rate.

Less is more? Should I let out the 134 that's in there?
Seriously, I want to get it as cold as possible. I have manifold gauges, I have a digital thermocouple meter for fast response. I just want to do the rest right w/o blowing it up.
I hear the pros on here charge by weight then final by vent temp to get it as cold as possible. So there must be some techniques they use w/o over doing it.
