My stock K16 car feels absolutely insane!! This makes no sense at all!!
Cobb maffless tune by Sam 1.0-1.1 bar
Speedtech 3" xpipe exhaust. No cats, no mufflers
997 coils and fresh plugs
SRM intercoolers with optional 2.5" inlet/outlets. (Biger plumbing is Very important and often overlooked)
Filters directly on the front of turbos (made a huge difference in power)M parts to arrive and I will get some real numbers for the car.
Wanna see just what these stock K16's will do.

Yeah, unfortunately and it's well past it's happiness date.
Stop trying to figure out If your car has magic pixie dust and go to a dyno instead of doing highway rolls with guys that can't drive.
Removing the intake piping removes a huge restriction, been saying that for years. Larger piping on the intercooler flows better but cools slightly less, I went standard sized piping but larger Y-pipe. Ask Sean to make you a Y-pipe next and do a plenum with larger TB while you're at it
You will have removed every easy restriction I know of at that point and I'd watch injector duty closely. I'd also not run any higher boost than that as you could be overspeeding the turbos.

Above attached is a pic of K16 compressor map. It maxes at 0.185 m3/sec, which equals 31.6 lb/hr. General knowledge says that 996 turbo's engine is capable of producing 9.5 crankhp / 1 lb/hr of air. So 2 x 31.6 x 9.5 = 600.4 crankhp at about 60% effiency. Very hot air that is... IRL 0.15-16 m3/sec is what they push. Close to 500 crankhp...equalling to that 450 awhp mentioned above.
Cost was around $150 shipped for 2 K&N's and 4 Dry Charger covers. The Dry chargers are great 'cause they add an extra layer of protection, plus theyre water resistant.(designed for ATV's and dirt bikes)
*****EDIT...only on 6speed do my photos get uploaded sideways!

bingo, dyno the car and be done with it
Bear in mind, boost pressure won't tell you HP. Compare someone with a freed up intake, freed exhaust, bigger TB, bigger intercooler, and swapped Y-pipe at 1.1 with someone running all stock at 1.1 and you will understand manifold pressure is measuring restriction too. One of the reasons why you test for boost leaks even if you're still seeing full boost, a turbo will push to reach its set point and can overspeed if there's a leak.
I agree that the dyno is the way to go, compressor map says you don't have the air for high numbers. A pic of the compressor blades might help folks figure out if you've got upgraded turbo. It would be really interesting to see numbers and figure out what's up.
