Too much boost = waste of money and time in our cars (Too much being more boost than your engine is willing to deal with).
I'm not saying anyone should do it but with the 10:1 pistons and customs cams GMP made a little over 300WHP. They were running a dual pass setup and tuned it for the setup.
Honestly I really think that alot of people are underestimating what a good cam setup can do when couple with other supporting mods like valve springs, good exhaust setup, P&P. I could see a LSJ making more power with these kinds of mods at 15psi than a stock setup running 21psi, if it can even keep running at all.

You might as well avoid this by sticking with stock compression and using the 100 octane tune and all of it's timing to make your power. There are many ways to make power; some are more risky than others haha AKA 2.5" pulley

i was out racing fri night and i felt a slight power loss, i at 1st thought it was heat soak on the blower so i took it easy after that. on the way home i pulled over to take a **** and on my way back to the car i noticed something on my fender, sure as **** it was oil! so i popped the hood and my dip stick was 3 inches in the air and there was oil every where! i guess thats what i get for spraying a 75 shot (actualy a little less due to low bottle pressure) ontop of a 2.7 pulley 
i did get a few respectable kills though before she went! a built evo with a white rabbit turbo, i put a solid 1-2 cars on him from a 40 roll and a turbo civic hatch from a 40 roll, i put train lengths on the civic! but anywho it just gives me an excuse to put the 10.5:1 compression pistons in with a new clutch and a few other goodies! just sucks that the car is down for a few weeks and im stuck driving my 11 second camaro to work

while into the spray im running a very safe 10.3:1 give or take. i have 60lb injectors too, if you dont have 60's on any pulley smaller than a 2.8 your dumb and just asking for trouble. my tune was very conservitive, but any motor no matter what you do can only take soo much abuse. and why would you not up your compression if you can? i thought our lower ends where good to 500 whp.

^^The lower end can, but it's typically not worth the extra hassle of tuning headaches. But if you know what you're doing anything is possible, and I'm sure you could make it work.
I personally would never up the compression on a daily driven FI vehicle, as I would rather have the piece of mind that comes with a nice sock or lower compression built motor. No worries that way at all. If I re-build I want to be god damned sure I won't be pulling it apart again later.

I am running a 2.8 and a 75 shot and about 12.0 AFR with no knock and stock timing.

Not that the rich mix is what is causing the high EGTs but the fact that if the mix is being commanded too rich your fuel system cannot keep up. Therefore you will monitor a rich condition, however a deprived cylinder will have a lean condition therefore causing EGTs to rise.
