That gives the backstory and the new logs from today. For reference, I've attached the logs here as well.

Basically been having some very random powerloss issues which occur right as I hit the gas from a stop or near-stop, which sometimes is followed up by an intake backfire.

GM & the dealership are working alongside of me (instead of against me) for once, trying to hash this out. Any input here is appreciated.

For reference, in addition to the usual stuff you'd log, I'm also logging "current firing cylinder"

For the record, stock tune, stock everything.

You need to log KR buy cyl. To rule out injectors. Are you fighting fuel pump issue's ????How is a log at WOT KR ing like crazy???

Are you talking about the jump that occurs following frame 490 or 3540 or both?
