under w0t is smooth and strong, perfect afr's and no knock. Idle is a bit lean / messed up occasionally but it evens out. Where I'm having problems is at about 5psi, 6000-7000 hz on the maf freq. The afr will go pig rich, then sweep all the way lean and the car will hesitate/stumble and give a couple random misfires. Only in this range I'm having troubles. I have no maf errors in these cells either. idk wtf is goin on.
