Well, your previous readings of a/f have ZERO bearing on your situation now.
You also are not answering my questions. You're in gear, at what rpm when it is bucking?
I'm asking some pretty simple questions, and getting a negative response. I'm not sure where your attitude comes from, so I'm done with helping in this thread.

The car bucks in first and second gear. Other gears are too tall to try and take of from a stop. When I say buck, I mean buck real bad. Not like the take off in too low rpm buck, but a 3000 rpm buck.
As far as A/F reading, there where for reference. The thing with the readings was it would go super rich after I would lift off the throttle (not normal. it should not dump fuel).
Also its a new cat.
The car will smoke REAL bad if I get on it.
Just for future reference. My fist mod on my car was a test pipe. It NEVER left soot on my bumper, it made it turn yellow.
The main purpose of this thread is to see if anyone on this site had the same problem.
I searched Honda-Tech.com and some say it might be rings, valve seals or a bent valve.
Agin, Im not getting attitude. You seemed to question me scratching your head when the aswers where right there. I now what a normal s2000 drives like, I had one at one time

I have similar symptoms as you. I think my "bucking" is due to a clogged fuel filter, does your car buck more when the fuel gets low or when you make a hard left turn out on full throttle? I believe the soot is from carbon buildup OR your car runs rich as hell. I have yet to determine why I have soot buildup. Im keeping an eye on this thread, let me know if you find anything out.
BTW who is the chick with the huge cans in your sig?

Another thing I read on Honda-tech.com was that it might be a timing issue.
Is there any way an AEM EMS might throw off my timing after it was taken out?
I dont see how, but Im usually wrong

Is it the same exhaust system that was used with the turbo? If it is, that is the source of all the soot.
Stock cars run 12-12.5 AF#'s under load, and blow out the soot in the exhaust system when you get on the throttle. Many other Honda's do the same. My car has done it since day 1, before a SC was ever installed.
