I was part of a dyno day for a local M forum, was the only S62 there. 15 BMWs must have gotten dyno'd.
If that's the case, it's easy to figure out if your dyno number is in-line. Are other cars hitting roughly what they expect? If everyone is running a bit low, etc. just use the same % scale factor and multiply by your number. It doesn't matter if the others aren't S62s.

How can you trust what the Dyno reported considering you didn't pull any fuses, yet the graph shows that you were still able to pull to 7000RPM? It doesn't mesh as it should only go to about 5600RPM with fuses 17 and 30 in place. You need to pull the fuses to fully disable DSC and allow to pull to redline.
Edit:Just watched the vids and your engine obviously revved to red line which is odd since you didn't pull your fuses.

When i saw there was an S2 on the dyno sign up sheet i wanted to come but things came up. It would've been good to have something else to compare even if my M5 is pretty much stock. Did you ask CTM what other M5s put down on their dyno?
From your dyno graph the AFRs look very good (around 13.5 which is what you want for an NA car) so i think it's just the dyno and nothing wrong with your car. Humidity was also high that day. There are a lot of factors to consider before thinking theres something wrong with your car. Other peoples number would mean nothing since they would be on different dynos, on different days under different conditions. Even if the graph is SAE corrected.
What were the E46 M3s putting down? Were their numbers a little low as well?

I told him my redline is 7300

Their were quite a few stock E46 M3s that put down 280.... so 333/280 = 1.189 * 378 = 450 hp
Hence why I felt that I was missing 30 hp and started this thread....But if other S2s put down 370whp on a dynojet then I feel a lot better still upset with DINAN for lying
For $35k it should be a lot better than phenomenal.
The rear wheel horsepower increase is absolutely phenomenal, the Price (IMHO) is highway robbery and was set when Dinan had a monopoly for one reason or other (lack of competitors among and that "BMW warranty still applies" crap)
