The ECU will cause the A/C compressor to disengage if you use full throttle (or perhaps less than full, but the limit's high.)
Don't forget that turbo cars are pretty sensitive to heat - that's why we have an intercooler. The knock sensors, in concert with the temperature sensors in the intake tract keep things from knocking, but the result is a loss of power. It's summertime, hot air means more chances of retarded timing. Could be other things, too.
