I recently added HKS spark plugs, BMS Intake, and BMS Oil Catch Can. I’ve been running map 2 on Costco 93 and it started off great. After only ~300 miles the car started stuttering only on very light throttle and would lose throttle response for around 3 seconds. This only really happens in comfort mode too. Whenever I do WOT pull there are no problems at all. Log is attached

If it happens in comfort mode, don't use it. This car is not for it, especially with modes and JB4.

Seriously, WOT log doesn't tell anything about your problem. Maybe try to log in manually when it happens.

How does the car behave after turning on cold and then on idle when it is hot?

Here is a manual log during just me cruising and trying to replicate the stuttering. The stuttering has not happened since this post (ironic) but I still want someone to look at the log in case something looks wrong.
