What is a "REAL" boost leak test?

Been trying trace down a boat load of Boost leaks after I installed a new FMIC and a small 20G.

@ WOT the car sounds like a broken gas main, and gives off a gaint PSHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH, sound like I've never heard before?

Why now, does this thing sound like it's leaking so bad?

And the car actualy fells a bit SLOWER than before?.....:-<

I've found a leaks off the the IC pipe, and the PVC valve and corrected or blocked them off.

The car still won't hold Boost, it leaks out almost as fast as I can pump it in with the compressor?

Cause I'm now finding leaks on biss, injector and TB shaft seals?

I've talked to a local un-named "DSM Guru" and he said that I'm being "anal" by doing the boost leak tests, and that these smaller leaks, like on th TB shaft, biss and injector seals, are too small to even matter, and that the turbo should "make up" for these kind of leaks?

My questions is what is a "REAL" boost leak test?

I've read else where that it should be able to hold it at whatever the amount of LBS od boost, that you plan on Boosting at WOT, and it should hold there for about 30 seconds?

Is this "anal" or not? Are the "smaller leaks" imporatant or not?


Many Thanks in Advance................


Howie
