It was I that mapped Gamers car on the dyno. I am slightly offended that someone would think that the results are being manipulated to give "Customer pleasing results"......
With the way that correction factors work if I had set a lower intake temperature then the correction factor would actually REDUCE the engine corrected power figure. (Cooler air boosts performance correction factor allows for that)
When dynoing cars the inlet charge temperature is not taken into account (Although it is an input to the ECU). Only the ambient air temperature, intake air (Air going into the filter) baro pressure and vapour point are taken to give correction.
Just as a bit of background info. I have been running engines on dynos (Engine test bench, rolling road & Hub dynos) for 10 years. This includes F1 engines, BTCC, GT-LM, WRC, Automotive projects, Jaguar, Aston Martin, Ford, Land Rover, Bentley, Rolls Royce and even some aircraft developments. I have commisioned dyno installations for automotive manufacturers that have cost in excess of $2M so you could say I've a done a dyno session or 2 in my time.
As I said I am a little offended by a couple of the remarks in this thread but I do understand that there are some dyno operators and dyno figures out there that are set-up to give "customer pleasing results" My dyno is not one of these.
As a last thought I would also like to say that BHP is irrelevent.... Its torque at the wheels/time that is important to me as that is what actually accelerates a car down the road.
