Default S4 Stumbling / Skipping at Low RPM!

I have an APR 93oct chip, bipipe, and TT DV's. I just had Audi replace the plugs because it was throwing a cylinder misfire code. Well all was good for about a week, and then it threw another check engine light and went into limp mode. Now after I reset the CEL, it starts busting up like the plugs are bad below 4k RPMs or so but smooths out on top. The car never hesitated and stumbled this bad. It happens every time I roll into the throttle or floor it - everytime?!?! Could it be plugs again already? Could they not be gapped right because I have a chip? Could a/some of the coils be bad? Any help would be greatly appreciated.

Thanks,
Daniel

Default unplug your MAF and come back and let me know what happens when you drive

if you have a bad MAF then your car will run smoother with it unplugged and it will get its fueling off of other sensors in the car. Go unplug your MAF, clear your codes, and drive the car (the CEL will come on because of unplugged MAF) ignore that. Let us know

Any fault codes? Blinking CEL maybe?

How many miles? Carbon buildup?
