No, I know that, but I mean after I get my custom tune, can I just up the idle a bit, on top of that custom tune? And then can I save that increased idle tune as a separate one?

So, I've got a buddy that works on cars a lot. I was in the market to begin tuning my 2017 Challenger (camming, tune, etc).

He's all worried about the EPA cracking down on "defeat device" makers, which seems to be another term for tuning tools (such as the Diablosport tuner) or tuners themselves ...

So I'm assuming it's going to have a pretty lopey idle.

My question is, can I adjust the custom tune and raise the idle speed a bit to smooth out the cam at idle? If I can ...
