I wonder if it'll get better over time as this is really the only time I've used the A/C since having the tune done and maybe the DME will eventually adapt. We'll see.
I think surging idle with A/C is a semi-common problem. I think I've had it before, and that's across multiple tunes...stock, JB4, now MHD. Betting it might be independent of the Dinan tune, but that's a guess.
