AMD dyno days I've been on work like this.
AMD chipped cars, fans infront of intercooler - lots of cold air & correct load. expected results.
ANother cars, fan about 3ft back & some pretty hard runs. numbers a bit low
Revo Cars, fans turned on just prior to the run - then major load applied & graphs heatsoak
They did it several times in the day - and of course the owners dutyfully write down their mods on the 'spec sheet' to give them a clue
That's downright dirty, but explains a lot. Doesn't explain Andy's results, but maybe he was just more vigilant?
I know the S3 guy with the Imolavirus turbo had it at AMD for something like three months (for mapping I think) before he pulled it and took it to see Mineah. Bad blood?
