aircon does make a difference, as does the heat. minimal, but it does.
the megs running crap, hi got heat soak?
My car feels very sluggish when accelerating with the air con on. Fact.
i guess we are nearly at the end of the summer... so this shouldn't last for much long!
The cup feels the same, although i now have a nice induction rasp around 6.5K and the exhaust note has noticeable changed, starting to loosen up good and proper, only taken 13K, and surprisingly the AC is actually quite good, better then the temperamental CC i had in my 172!
