People, almost every dyno has SAE (or maybe STP) correction factors built in. You don't dyno lower because it is hot.
That is a large gain for the mods, but the 330 is exactly I would expect with the 287 being kinda low for a newer model, even an A4.

Yes, the SAE correction factor takes all pertinent variables into account. So, since it was done on the dyno it should be a relatively accurate 43 hp gain, assuming there wasn't a spike taken as the highest number or something similer to that....
