Psi is dependent on the waste gates adjustment, BEFORE you mess with it, search how and why here first.
An ats will easily hit 15.
Your egt's are way more critical, as stated above, piston damage begins at 1200 degrees
A safety margin @ 1100-1150 is well advised.
Hit the stickies and read up.
The closer to 1200 15 vs 30 the better it will read visually for you
Bigger hash mark separation and you will lift off the closer to the end of the sweep versus the middle of the gauge
Here's a tip...
Set the point on the individual gauge corresponding to the max poit / limit at 12 o clock, that way a quick glance will get you the information without reading the numbers.
Redline, maxed out , is straight up and down.
