The stock throttle table on the Z is fairly conservative and doesn't really give you much throttle in 1st or 2nd gear at low RPMs. As for the A/C, it's going to rob some power if it's on. And damn, it is hot this week in CA, isn't it? Supposed to be 115 this weekend at Buttonwillow. In my experience, the engine will start to pull timing at 230F oil temp, so no surprise that it's running sluggish in this weather.
