[QUOTE="mikeeg02, post: 1472713, member: 24194"] I posted videos earlier, and I can repost them again if you'd like. But with my setup, (and loaded heavy) I can make a smoke free ~15psi at 1,500 rpms. ( not that I'm advising anyone to do that) but this turbo spools up really fast on my truck. I completely agree about your theory on gating off the back pressure, and I see the same thing, the turbo basically parks at ~42 psi, and as soon as it hits ~40 psi the back pressure goes up, and on my setup its to ~65psi. Which is 1:1.6, (which isnt awful) and only seen (for me) in short bursts. If I was competing with it, it would definitely be gated, because like you, I think its from a restriction on the turbine side. But since its such a rare occasion for me to be in that situation, it doesnt bother me. Also, I have seen both boost and back pressure climb faster than one another. For me, it seems to depend on the situation, but they are generally only a needles width apart from one another up util 40psi. [/QUOTE]
