I'm in Denver, 5200'.
If you want a direct comparison to Paul's car with the Cobb tune, drive down to Dynopro and put the car on the rollers there. It's $75 for a half hour on the dyno if I recall. This is where he had it done. His was a canned Cobb tune using stock K16s on 91 octane and 1.2 bar. Stock intake and a 3" catless exhaust. If I recall, looking at logs, the canned COBB tune was pretty rich and not optimal for our altitude. If your car is AWD, the front driveshaft will need to be disconnected.
Yes, it was definitely rich, and I'm absolutely sure Sam could tweak significantly more power out of it, but it has been pretty bulletproof and an absolute blast to drive for the past few years. Nowhere near the power of Powdrhound's build of course, but the torque is just a hoot! I enjoy driving my 996 Turbo through the mountain twisties every bit as much (on certain roads more) than my (also tuned) 991 Turbo S.
Not the same dyno run, but the same day. Chris C. running through the gears in my Turbo. Did I post this earlier in the thread?

That is about what I figured last year, around 530 at the crank, however, richer than John's tune... much richer. 11.8/12:1 would be closer to the AFR I would expect to see.
