Here is a dyno graph from a car tested at TVR power in the UK



We tested the same car hours earlier on our own dyno also.

Dyno graph of SAME car on same day:



A very well known forum member in the UK was present at both of the tests as the HP was being questioned on our dyno (too low). This was due to the Supersport tyres reading extremely low on the Dyno Dynamics (a well known problem in the UK with E92 M3's).

Notice how the two graph shapes are IDENTICAL. The boost reading from our machine is as it should be, nice and smooth. The boost reading from the Dynojet is wavy (for what ever reason).

Dyno Dynamics read low anyway but the effect on this car is exaggerated due to the Supersports.
