Everyone read this!!
This is great info; I'll make sure to check mine after my intercooler and piping upgrade next weekend, and before any future tuning. Thank you to everyone that contributed useful information.
Here is my travel set-up when not working on cars at my garage or shop.
Air tank, hose, in-line air regulator, spray bottle with soapy water, adapter made from home depot racing

Remember when testing, use the soapy water because you can't hear boost leaks unless they are big.

There is a write up on here I believe. If its anything like the evo 8 bumper, the front bumper comes off easily in 10 minutes if your taking your time. Its only a few bolts and some plastic panel screws. One thing I do is zip tie my oil dipstick tube just in case it decides to pop off during a boost leak test, and leave the car in neutral with the parking brake, not in gear. I actually had enough pressure in the system to want it to turn the engine over and the car wanted to creep forward on me. Otherwise its pretty straightforward.
I have never used one, but some people here do. I think a pump might not hold enough air to keep the system pressurized unless you can spray and pump, spray and pump.

Also-
ANOTHER important note,
use soapy water between tbolt clamps and the coupler you have them installed on! That helps the clamp to slide under itself easier when you tighten it, and will prevent pinching of the coupler!!
To check the IC inlets and outlets is enough with a pressure test to hear a leak, sometimes if the undertray is on, you can remove that by itself to fix it, makes it easier when the clamps are in the right orientation so that you can get to them without removing the bumper!

I always boost leak test my car after messing with anything with a bottle of soapy water and air hooked up to the turbo. But before a tune, I let the pros look it over. Nice to know CBRD is so thorough as they are doing my next tune. 
Same issue as yours. According to the Cobb article referred to in the first post, you could use a bicycle valve instead of a compressor valve. I have a tire compressor that I figure I could use, just need to figure out where to get a proper valve and install it in the pipe cap.
I need to do this because my new CBRD BBK Full turbo set up went south (bad idle/stumble/stalling) about a week after they installed it, and being I'm about 6 hrs away from them, I need to do the troubleshooting myself. CBRD did find a leak in my TB and fixed it during the install - no one had found that one previously. I had MIL.SPEC rebuild that TB and when it came back with new shaft seals I had to turn down my boost since I no longer needed to compensate for the leaks there. Word to the wise - if your TB is 4 yrs old or older and is using the OEM shaft seals, I guarantee they're leaking.

lol, i did a boost leak test on my car thought everything was perfect and even told Chad i did but had him check anyway before he tuned me and he found leaks that i didnt hahaha, so def have a shop do it. better yet just take it to CBRD!!!

make sure you use some kind of glue when securing the pvc cap to the hose. they willl pop off if you dont.
we put a good size hole in my buddies finger when the cap blew off of mine.
