As I mentioned in the post, i multiplied the raw numbers (369hp and 500lbft torque) by 1.20 - number which I pulled out of my a*s.... Which would give me the 442hp and 600lbft torque. This would account for a 17% loss of power and torque from the flywheel to the wheels... which I think is certainly reasonable for a 4 wheel drive vehicle with automatic transmission. But like I said, the reason why the hp is so low is because the truck was struggling for air at the high rpm's/speed... I am almost tempted to go back and re-dyno it with huge fans in front...
Overall, the truck is AWESOME and I am VERY happy with it... I had a 2008 Jeep SRT8 which I just sold - the pickup on the X6 is AMAZING when compared to anything else out there I have tried out... In some ways it feels more aggressive then my SL55 AMG - which has 515hp and 540 lbft of torque - especially at low rpms 2000-3500....
