Real world gains are always different from the dyno. This goes for any part, chip, exhaust, etc, as load at speed is different as is air resistance as speeds rise.
A dyno fan will never replicate air flow at real world speeds, certainly not at 85 mph and up as who other than a Formula 1 team has access to that kind of wind tunnel?
The fan and dyno helps us get an idea of the added flow and how the car responds. I ordered a Vbox to give 60-130 numbers, and there are plenty available on M5board (for the M5/M6, the M3 obviously has not had scoops available as long and hasn't been available as long so it will be some time before we have as much data to reference). I will do what I can on my end to add to the community with my own data, dynos, etc. I'm sure others will be adding results as well over the next few months.
