I know this is an old post but did you ever get your tune resolved? I also just installed a procharger ho kit with the supplied tune from procharger in my 15 Mustang GT and its doing the exact same thing. When gets up to normal operating temp the idle starts surging at 2500 rpm and I gotta tap the gas for the idle to go back down. It does it when i come to a stop or just idling. Procharger has sent me a revised tune and it is still doing it. Just got done data logging and emailed it off to them.
Im new to the coyote mustang world, had 2 new edge stang procharger with the procharger tune and never had issues.

If you are still having issues with the way the cars running, and the Procharger tune hasn't been running to your liking. A Jon Lund tune might be something to consider, he's quite familiar with boosted gen 2 coyotes. Also, if you got the HP tuner module through pro charger, he would be able to tune on that device with a simple firmware update.

My cars been running like a top since day one on my Paxton, tuned by Lund.

Canned Procharger tunes are horrible. I wouldn’t hesitate to go with any other major tuner for custom tune
