could it be false?

Can I please get some comments on the attached PL files. They were recorded the other day from a standing start. I'm just starting to get a handle on this and am wondering if the knock you see could be from the 2-3 shift? If not can I get advise on how to eliminate it.

Your help would be greatly appreciated.

So, I'm seeing 31.6 PSI of boost? and then you jump out of it before it hits 3rd gear. Right?

Are you running 93 or some race gas?
