I'm worried guys, I have a track day booked at oulton park and I have been out this evening and tested the db's.

Ek9 b16b

Js induction
Mugen manifold
Mugen twin loop

Did 2 tests stationary I got 102 and 105 at 5500rpm and that was a decibel meter. Also did it with iPhone and that read about 94-96

Drive by with the meter was around 88 - 95.

So my figures don't conform with most others, is my devices inaccurate? What rpm will the stewards test at?
