Sluggish In Hot Weather and AC On

I've been noticing on hot day 85+ degrees with the AC on the car just feels sluggish. Throttle response is way off and the car just feels slower in general. I know turbos aren't as efficient in hot / humid climates but man I feel like it shouldn't be that bad. Do you guys have the same experience?

Yeah, similar experience here.

Running AC puts more strain on the engine which is already suffering from the effects of heat soak in warmer weather, so what you're describing sounds normal to me.

Granted, how that effect feels to the driver is subjective, but in general hotter weather + AC on will make the car feel slower/less responsive.
