I need the extension to take out the spark plugs, that's what I was referring too is all. Making mental note by typing it out.
and I said I go WOT when getting on the highway, and I do whenever I merge. That's when I noticed my boost going down from time to time. I have no problem admitting how fast I drive and where I do it at. To make sure I wasn't crazy when I noticed 15lbs instead of 17, i did a few 1st gear WOT pulls coming out of my apartment complex to make sure I had accurate information.
I also don't have a G85, just the regular SS/SC.

when its hot the air molecules spread apart and are
also tuners do not generally mess with the trims when cruising or not using boost, those all stay the same thats why stock cars don't need fuel adjustments because those tables are never changed. the only thing tuners adjust is the fuel trims when at wot.
i have an ls, and when i cruised i was around 14-15. i still am right around there now even though im supercharged. that is not something vince messed with. the only part that was changed is wot, instead of being around 13 (if i remember right)or so when i used to floor it before i was charged its now at 10.5....which is still off. should have around 11.5ish

If that didn't make sense I can try to explain a bit better. I'm just throwing that out there for information's sake.
Although all this talk of lower than normal boost = blowby kinda makes me wonder if my rings really are fucked. My oil's smelled like fuel for a while, but I recently switched to a smaller pulley and my WOT pressure didn't change at all.
You are pretty much right. They are supposed to but they FAIL miserably at doing so
