Evo x idle rough
Hello people so I have read a couple of posts here on idle issues and can't seems to find any solution.
2011 EVO GSR
39k miles
Stage 1 Cobb with CHFF
So when coming to a stop ( rolling 10 mph in neutral ) rpms stay high around 1.4k and slowly will go down to 900 after I 100% stop ( sometimes will bound between 1.2k - 900 for 2 second ) . I have checked all lines no leaks that I can see or hear. I also have checked the line near the oil dip stick that is on tight. I had the same issue when I was stock but not as dramatic it would idle 1.1k then go back down.
Am I missing something that is on here ?
Or could it just be the flash tune ?
I have been driving with the flash tune for 2 days now.
I had a turbosmart BOV 50/50 installed on first day of flash tune and it would not close all the way even on tightest setting. So I took it off and put the stocker on.
Please help !!!!!

This idle behavior drives me CRAZY.
Tuner said there was nothing he could do, it's just the way evo's are. I feel like he knows best, but there has to be a way.
I test drove an evo that was tuned before I bought mine (stock) last year, and it did NOT do this.
I've searched and searched and never found a fix related to this exact issue.

Mine has done that since the day I got it.
Always makes me look like a shifty noob until the engine warms up too. Never had a car that couldn't compensate for the engine temperature like this... I sometimes wonder if it's for these reasons that Mitsubishi is slowly dying in the US.
I also love the (apparently normal) "mivec drop" the car does sometimes when pushing in the clutch while slowly rolling to a stop...
Cant get enough of these drive-by-wire throttles.

On cold start it idles all over the place..
When warmed up, if cruising and I press the clutch, idle will drop to ~700, then come up to around ~1300 and stay there until I'm totally stopped. That's when it comes back down to 1000. Might just be something I never get used to
For reference:
