Default My ASR cuts off when AC is on

it didnt start doing this until after my tune by tsp. That is the only thing it does, and it will turn off a few minutes after you turn the ac on, and you cant turn it back on using the button. I always turn my ac off when i shut off the car, and when i restart it is fine again. Any ideas as to why it would do this?

If you turn the ac off, can you turn the ASR on/off then at all, unless you restart?

i usually have the ac on until i stop the car, so i dont know if it will let me turn the asr on again if i turn off the ac while its driving. Most of the time i reach my destination with the ac on, and turn off the ac when i shutdown the car and when i get back in the asr is fine again

its probably throwing a code like P0121, that is the manifold pressure goes out of range when the AC is on is due to the extra load on the engine with the cam.
