During a few moderate pulls in 2nd and 3rd gear (3000+ rpm always before pulling hard) my car cuts power, and CEL comes on. When I check the codes, this is what I see. Recently installed ARM catted downpipe ~2 weeks ago and had no issues until I updated to IE stage 2 flash (upgraded from normal stage 2 flash to their new update, Pro Stage 2)

Running 93 Oct, aftermarket air intake, ARM 3.5” catted downpipe, with no other performance related mods.

Any ideas as to what’s going on? Been trying to pinpoint why this is happening. It has happened a total of 3 times since yesterday.

I am ALWAYS making sure to use 93 Oct from Shell gas stations. USA east coast
