How much AVCS accounts for is difficult to judge, but the turbo performs like many similarly sized turbos.
It's not a bad thing, it is what it is.
You are right, there are no direct comparisons...which is why your 'just another 20g sized turbo' doesn't make sense. Not trying to start a fight...i just don't think it's a fair statement or comparison after only having seen a single dyno graph. As stated before...it spools like a 7cm 20g and makes more power than a 10cm 20g. So i guess you're right...it makes power like a 20g...all of them.
The compression bump does not come close to spooling this turbo the way AVCS would. I'm getting one of these in Nov. to put on my wifes 2011 Sti Limited. So we'll get a little more direct comparison then.
