I had Mike at MotoEast check the logs and he adjusted low-load, load RPM timing. Initially it seemed to help a bit, but I think that may have been placebo.
I've checked for vacuum leaks and boost leaks but haven't found anything thus far. Any other thoughts? Should I try swapping map sensors (I have two stock ones)? Reset the ECU? Any other thoughts? I didn't have this problem prior to installing SC, so i'm not sure if it makes sense to be related to spark plugs or injectors?
Car runs and idles just fine -- but the random 'torque dips' (as I like to think of them) are making me wonder.

Just make sure to warm up your oil to at least 150f and it shouldn't stutter after that. Mine does it anytime the engine is cold.
