Rototest are normally not working with private persons as customers but are willing to test a car for 2000 SEK ($300). He also told me that the best thing would be if we hooked up with a car magazine in order to get some more weight on our test.
So what is you opinion about power and lag with the 29.2+ software, is it a lack of power below 3000 RPM or are we fooled by the lag? I think we miss a bit of torque together with the lag.

I'd contribute to the cause, if it is done right. Rototest is the only dyno I've seen that almost perfectly replicates BMW's advertised curve.
Do they do the dyno test at WOT for all RPM? Or is it a gradual acceleration?
