evo 8 turbo vs evo 9 turbo

That doesn't make sense - others have reported about a 200rpm loss in spool on an VIII. Even if there was a 200rpm gain in spool, it wouldn't be described as "incredible." Interesting...
I dont understand too. when i had my stock turbo, i would see 22psi at about 2900rpm. now i am hitting 24psi at around 2800rpm, that is, from what i can see from the gauge. but ignoring the gauge part, i can definatley feel it. I LOVE IT!

when i dyno'd it and pure tunning's MD dyno, i made 300hp/312tq with afr @ 11.5. they said its configured to read 10-15% less than a dyno jet.
So i slapped on the evo 9 turbo, removed the rmr licp (will not fit with the 9) and added the rmr uicp.
I just came back from BR's dyno, and i made 289hp/276tq with afr @ 11.8. From Buschur's post, his dyno read about 20-25% less than a dyno jet.
Whats intresting is that i made lower torque than hp this time. It could be because of the stock licp, so i will see.
Hypothetical question for y'all, and slightly OT:
If a stock Evo8 turbo can make a 2.0L I4 hit full boost (19psi) at ~3250rpm, wouldn't it be reasonable to assume that it would make a 2.8L I4 hit full boost (~10psi) at ~2250rpm assuming it had a low-backpressure exhaust and small (stock) cams?

Oh, and btw its C6H5CH3
