if the compression is low and the intake temps are reasonable, would 30psi be anything to worry about? with octane to support it? i see most people stop around 22-25psi on here.

Well it all depends. The MOST important question is how much timing are you running?

30psi and 10 degrees is way different than 30psi and 25 degrees.

im thinking about trying 25-27psi and 15* timing to start, 110 sunoco and 28g/hr twin nozzle meth injection. or would it be better to run 23-25 psi and 20* timing.?

The more timing you run the more cylinder pressure your going to make which will eventually lead to pushing coolant. I run as much timing as possible at every boost level.
