But I am shocked at the lack of pull as the rpms get up there

Just put in a few gallons of e85 and all of your complaints will be addressed.

load put an e30 map or even run stage 1 aggressive it should run great.

How is it not accurate? I think you are confused.

Last time I checked twin turbos are part of the engine. Thus, N54 twin turbo.

If you modify the stock engine in any form and fashion then yes there could be possibilities of getting some more top end. I highly doubt it would still rev to the point of S65 or S54 without huge internal upgrades as well as turbos.

I guess it depends on your definition of top end, but when you talk to N54 people usually that means wishing it would make power to redline instead of falling off at 5500rpm when the boost is turned up. By that definition all that's needed is bigger turbos and a tune. Sure, there's other hardware to change if you want to run 8000+. Once it's simple to run big boost on big singles then maybe it will be worth working on the hardware to run 10k+ rpm.

I added the HPF FMIC , AR DPs , aFE DCI, and man on man did it make a difference with the Cobb - ... next step for me is charge pipe

I'm pretty sure 8k is revving past 6k.
