You need to get that Wideband running asap. You could be washing down your cylinder with fuel. At least that was where I was before I got a tune. Your car uses stft and VE under certain RPM's could be stumbling over the table and after coming out of closed loop or dropping off MAF to VE. You should be able to idle on 80's at 800 rpm. YOur idel could be high though if your car doesnt go back into open loop. This was something I was seeing as well in my tune after having a few people trying to help me tune the car.

Shut off dfco and force the car in open loop and get ur VE and MAF tables dialed in then Turn the dfco back on..
Ur eather going stupid lean or pig rich wen the car comes out of dfco.

Drove the car for the third time today, idles better. I don't understand, it runs fine when I start it up. As soon as I get about five miles from home it starts misfiring and running like ****. Oh well, got the clutch broke in enough for tuning and it's gonna stay parked until I can get tuned.

I'm sure the head added with the new intake is the culprit. How did you tune before without a wide band?
If idle is becoming a problem, you could just unplug the o2 sensor for time being.
Force it into open loop
