anyone ever seen any independent dyno results?
To a certain extent they meaningless... They depend on the operator, software/hardware and vary wildlyDragy 100-200kph is where its at. That's real world performance.
This is my db9 phase 1 and DBS diff
The vantage s below mine has VAP manifolds
autotopNL youtube channel does vanquish mk 1 and mk2 runs and gets 11 secs and 8.5 secs respectively

they're not meaningless, same dyno, same settings, before and after.Dragy 100-200kph is where its at. That's real world performance.

A high quality roller dynamometer is an excellent tool - but very expensive.
Please be aware that data interpretation is difficult. Peak power should not be the target, increased power across a wide range of revs is important, and at the same time drivability a lower revs should not be impacted negatively.
The benefit of tuning measures are indeed presented meaningful in an 100-200kph drag - because this procedure uses a meaningful range of revs, includes the capability of reving up (light flywheel) and includes one or two gear shifts. It avoids the slip and traction problems of a 0-100kph drag. More interesting may be 1/4 mile or 500m comparison.
Same settings are important for all evaluation concepts. For a 200-300kph you will have difficulties to achieve this due to temperature changes, barometric pressure, wind direction changes, temporary wind gusts and so on.
A good dyno may handle the barometric pressure issue and will not be impacted by wind and will actually have variances of only 1%.
I would be highly interested in a modified real world drag: 100-200kph with manually initiated gear shifts at exactly 5000/min.

Google > pistonheads > project blowfeldThere's a few others but I cba to trawl
Seriously though, the mods do exactly what they say on the tin. BR are probably the most established aston tuners around and have been selling them for over 10 years.. if they underperformed someone would have called it out by now.. you won't find anyone that has.
