This is like a new IS250
I must say I just moved from Colorado Springs (my old house is at 7000 ft) to San Antonio, Texas (700 ft) and the difference in the performance of my car is night and day!
I am now actually happy with the 250's response/acceleration. Def getting a new exhaust still, but now will stop lamenting that this car is slow--i feel like it gained 30 horses!
Just had to share--I am soooo Happy!

Same weather at 700 feet is about dead on at 100%
IS250 is rated at 204 hp.... * 0.76=155.04 engine hp.

I'd be curious to see how Kurtz arrived at that number. I'm not doubting him, but his figure doesn't jibe with the estimate of 3% power loss for every 1,000 feet that I've always heard.
If I lived at that altitude, I'd definitely be driving a car with a turbocharged engine. Turbocharging largely compensates for the change in air density.

I also live in Colorado Springs and the altitude definitely sucks in terms of automobile performance, especially on 'hot' summer days. Of course our hot summer days must feel like the South Pole to a hot summer day in San Antonio. lol. Forced induction is a big advantage up here. My 350 runs even, if not slightly faster, with my friends stock 2009 WRX for reference.

I don't know what you mean by "29.92 humidity", but I assume you mean the atmospheric pressure. 29.92 inHg is the standard pressure at sea level. You lose about 1 inHg for every 1000 ft so at 7000 ft, you will only get about 23 inHg. That's 76% not taking into account the temp or humidity. So yeah, that's a lot less air going into a normally aspirated engine even at full throttle and a lot less power.

And FWIW, the pressure right now in Colo Springs is 30.03...
