Probably the tranny downshifting. I'll try this on my 6MT and see what happens. Are you in top gear at 40mph or something close? At 40 I'd probably be in about 4th gear or so. Maybe fifth. Obviously in third, the car should take off immediately for me.

Maybe try with the tranny in sport (manual) mode so it won't downshift on its own just to see if it's really just tranny lag. If so, there's not much you can do about it other than apply the gas smoother.

Another item....when does the blower kick in.
Almost immediately from my understanding. Around 2K rpm or so.
