Real BHP & BTQ for the 3.6L Pentastar?

I've been watching the CAI threads and I noticed K&N had dyno restults
for the 2011 3.6L Pentatstar 203.76 HP/BHP 194.74 TQ

http://www.knfilters.com/dynocharts/77-1560_dyno.pdf

Note: no other information given on the test, applied dyno correction, ambient temps, FWD or AWD test mule, etc..

Jeep claims flywheel numbes are 290 horsepower and 260 pound-feet of torque. They don't provide the real numbers often refered to as "Break" HP or TQ.

It's a fairly comman standard across all automotive manufactores and aftermarket guys flywheel to Break usually accouts for min/max 18% - 25% loss in these numbers due to drivetrain.

@ 18% loss that would be 52 HP difference (238 BHP)
@ 25% loss that would be 72 HP difference (218 BHP)

So.... where is the missing HP and TQ? it's WAY off based on the K&N dyno.

Anybody have any Dyno test for their 3.6L FWD/AWD? I'm scratching my head on this one.

FlyinRyan - Have you done any dyno test while testing out your mods?
