I was just thinking the same thing this week...I live in NY too and ran the A/C hard. I got too used to driving it with no A/C and now that I need it...powerloss. I usually cruise with windows down on the hwy, but this week I needed the TB around town and the loss of acceleration is quite noticeable. It dogs thru first and until upper end of 2nd gear and then takes off, shifts, then dogs until the mid range of 3rd gear and takes off again, shifts and has no noticeable loss afterwards until it drops a gear or two with traffic and lights. I'm assuming that's just the way it is...nothing to be done. I'm still getting 14.5-15mpg mixed driving with A/C on and being slightly heavy on the gas pedal.
