Is this normal? I've noticed I can't blip the throttle like I used to, it stays revved up longer. I don't know if it's because I changed gas, the hot weather, is this an emissions thing? Or do I need to reset the ECM?
It's not every time but seems to be more often.
Edit- manual trans of course.

Did you have the update done? On my 2018 I had the update completed and it helped with the rev hang. Now with my 2022 Altitude the rev hang is way better but the throttle response may sometimes feel laggy!

I don't want laggy. No, I haven't been to the dealer yet for the update, but this is also a new behavior after 2 years. I may just disconnect the batteries and do a hard reset.
