Why are we going to waste dyno time doing compression and boost leak tests? I was planning on doing these one more time the week before the tuning anyway. I believe my friend Tony, who is a master mechanic for Nissan, knows how to do a compression test properly and the boost leak thing is not rocket science. I've already boost leak tested twice and everything is tight with the exception of a small leak at the passengers side turbo housing. Probably needs a little RTV like in your TT.NET write up, but I'm not about to pull the whole motor out again to get the turbo out and fix a small boost leak. Goes up to 5 psi no problem with a small air tank and then takes about 30-60 seconds or so for it to leak back down to 0. Thoughts? I know you're gonna have them. :-)
