Does your Redeye idle smooth?

Hey gang, I was wondering if your Redeye idles smoothly?
Also wondering if anyone has changed plugs and noticed any difference? I don't want to replace plugs just for fun!
Wile at idle, there is a bit of roughness that I can feel. Not sure if it is just the HP nature of this engine or what. I have just over 12000 miles on it and drive it as hard as it will run probably more than most on here. Not mistreating it, just getting all the performance it will generate. Seems like the performance has dropped off a bit, but maybe I am just getting used to it. Need to get it to the 1/4 mile dyno with good track prep to confirm.
Thanks in advance.

Is it possible you got some bad gas?

Mine idles real smooth at almost 11k miles, it is a little lumpy and shakes a little, but the engine seems to hold a pretty constant rpm and idles easy IMO.

It has done this pretty consistently. I've been thinking it is just the nature of this beast! I love this car!!

This is a seat of the pants thing. You can feel it, doesn't make a noise. It ies smooth, then a couple bumps, then smooth. Not consistently bumpy, but the pattern is consistent, as if only a couple cylinders.
Probably normal, just thought I'd ask you guys. The M6 HC Challenger I drove for the weekend at Bondurant was smoother, but they were using black keys. I wouldn't expect an idle difference regardless of mode, but maybe there is an initial timing difference or something. I don't want to change 16 plugs at 12000 miles for nothing, but that would confirm it. Just getting into racing season, so want to figure this out before. The car has run a best of 10.55 @4720 lbs with me in it and M/T ET Sreet R 305/18 with a 1.50 60'. Probably has more if I can figure out how to drive it better.) and has gone 195mph before running out of room (closed course of course), so it is no slouch. Just wondering if plugs need to be changed more often on the Redeye.

I only have about 3000 miles on mine and it idles pretty smooth. I have around 200 passes on the car. It did have a little bit of a rough idle after taking it out of winter storage because of bad gas. I ran the tank down low then put in some 94 with some octane booster and @Hpindy flashed the computer to reset the adaptive's and it was smooth again. Maybe try resetting the adaptives? If that doesn't work maybe then try the plugs.

Given that you drive it hard, I would change the plugs every 12k miles anyway, even if that's not causing your rough idle.

How do you reset the adaptives?
Thanks

You could get your dealer to do it next time you go in. They will be able to do it for you
I had a forum member do it for me. @Hpindy might be able to explain how to do it.

Have you ever put raceway gas in your car?

Nope, just Tier 1, mostly Shell Premium 93.

I used HP Tuners to reset Markp's adaptives and throttle relearn . You don't have to unlock the Ecu for that but you will need the bypass cable . I used the Z automotive one that goes in the trunk because it was easy to install temporarily .

My '16 has always had an 'lumpy' idle, same as you are experiencing in your RE. I just assumed it was the nature of the beast. Kinda like it actually, vaguely reminiscent of an old school cam'ed muscle car ;)

Same with my '15. It makes the wife nervous...'This thing feels like it's just going to take off on you!'
