The AC is a huge drag, but I seem to remember that the compressor clutch lets go at WOT on these cars. It would contribute to part-throttle lagginess though. And since you're more likely to use AC when it's hotter out, that could very well be the issue. On other cars I've seen dynoed up to a 15whp difference between AC off and AC on.
