Just a thought and I hope someone corrects me if I'm wrong but....

I've never done a dyno day before, and I noticed the guy corrected all our figures off ambient air pressure which went into the air filter, but I thought in a turbocharged car you wouldn't be able to correct it because that ambient temp is then heated up during compression in the turbo to x degrees and then cooled via the intercooler to another temp. Just done a quick bit of reading and apparently you can't sae correct turbo engines? So we should be gloating about our non corrected numbers instead?
