Calculated from the datalogging (which comes from the MAP sensor), I got 28 psi. For 0-60, it's interesting that they don't just include that on the 1/4 mile performance report. I have them in the Dragy app, though. I did a total of six runs, they range from 5.87 to 6.33, but the 6.33 much higher than the others. An outlier, I think. Next longest is 6.07. Average is just a hair under six seconds, with the outlier removed. Might as well just say six seconds.
Drew saw the video and found 1/4 mile times for other W211 cars, though gasoline engines. One was 14.3 seconds at 99 mph (very close to mine), and their crank horsepower was 302. Knowing that my engine is 150 pounds heavier, but otherwise a good apple-to-apple comparison, looks like my car is a probably a bit over 300 hp, which I didn't expect. I had figured I was at about 280. Drew's done a nice job squeezing what he can out of my car without the further hardware upgrades that are coming! The high pressure fuel pump and injectors are stock.
On the boost I went with the peak of [what I saw as] 2855 hPa. At idle (just atmospheric pressure) I saw 1025 hPa. The difference [1830 hPa] is what the actual boost is and I get about 26.5 psi when converting. If you're under 6 sec then that's really pretty impressive; I'd think that the TCU mod is helping as well. Did you have traction control off? You now have me considering a Dragy: there seems to be two models out there now and not sure which one makes the most sense (cheaper and more expensive of course).
Peak boost looks to be about 26 psi? Do you have times for 0-60? I'm guessing it's between 6 and 7 seconds based on the video but it's not a real precise guess (not enough granularity going by video time).

That's a better way to calculate it, going with your number.
