When driving with my A/C on, when I go to pass someone or give it some gas on the interstate, the A/C will change smell, and the cold air will stop. The HVAC stays on and the a/c light is lit, but the cold air is gone.
Some times it will come back after 5 minutes, sometimes, i might have to turn the HVAC off for a minute and turn it back on.

Suggestions?

Stock ecm is setup to turn off the ac at >90% throttle opening. My Overkill tune disengages the ac at >50% throttle. Prolly doing what's supposed to do.

Normal. System is designed to give you full worp power first. A/C returns when your ship is out of danger (reduced throttle)

I doubt its normal if it's cutting out for minutes at a time. Unfortunately, I can't add anything more.
