I know these things are running ridiculiously rich, but I'm kinda concerned about the carbon stuck to the back of the car too. Any body else look in their rear view mirror and see the big black cloud that gets emmited from the tail pipes? Mits needs to give us all a free tune

 

I got a ww and black carbon is real bad now with different exhaust

 

that is exist in the evos from day one.... I always had to was the rear bumper.. looks like you have an old diesel car when you park it

 

Better too rich, then too lean for sure.

 

Nothing much you can do I guess. I still look for that puff when I jump on my IX....especially catless.

 

IF you watch the top gear video the fq400 puffs a mean cloud of smoke on the straight. The only reason i bring this up is because that car is the godfather of all evos so it must be ok. Well thats what i keep telling myself anyway.

 

I wonder what the AFR is for the B411 is. I know most states that require smog don't require it on new cars for 2 years. What happens then, it fails. Does Mits know this could be a problem? If so, are they gonna give us a tune to cure it before we all start failing?

 

Haven't heard any guys around here, that I know of, fail smog due to this on the older Evo's.........but I don't know I guess it could raise a good question.

 

not a big change from the previous evos
