If the tyres weren't up to temp then they will have a slightly lower pressure. This should only have a minor effect when the dyno is trying to calculate the coast down losses to convert wheel hp to crank hp.

The above again assumes that no tyre slippage has occured on the dyno.

The dyno dynamics RR works on a default loss calc, there is no run down loss check. I enquired of JKM after everyone had gone, as I was curious to understand how they work out the losses on a DSG, which to my knowledge isn't meant to be turned at high speed in neutral.

His issue was down to dsg, the power was similar before and after...

....That's right - DSG and kickdown. Found not to be an issue but JKM wanted to be sure what was happening.  :happy2:

....Me too - I need new fronts. I check my pressures very regularly though.
