Both a K27 7200, or a K27 7006's boost will taper off as revs go up just like your graph shows. They just run out of breath.

If you install a K27 HFS then it will hold max boost all the way to redline, even in 3rd gear... and you should be a little richer up top, like around 12:1 or even 11.5:1 if you go that route.
Or it may detonate and break rings, burn pistons, and all that fun stuff.

I would recomend Brian's RPM switch and solenoid and adjustable WUR too...
The 930 WUR gives enrichment when it sees boost no matter what rpms the engine is turning, so you delay the boost pressure from getting to it until around 4500 rpm with the rpm switch and air solenoid.
