Post that log.

I am a bit hesitant to go do a full 3-4 pull because I am not sure it will make a full clean pass and the knocking event scares me.

In the log I posted, from timestamp 750 on I was WOT 2-3 and I hit a hesitation at ~5500 in 2nd and hit a wall at 6000 in 3rd. I did another pull after that (850) in 3rd but pull out at 5,800 because again just something wasn't right.

Do you have any suggestion on what could cause this knock event? Do the AFR's look good? It seems like Boost has tapered off quite a bit by the point where it is getting these hesitations?

The only thing I did see that looked off to me on the JB4 is the FOL value is set to 0? I am not sure if this is just normal when you have a BEF?
