Knock is normal..it is timing related.Mine does it also..No need to worry.You should be seeing roughly 28 to 32 lbs with that tune and your set-up.

Do you need a boost-fooler to get those boost number, and what did you do for your tranny

[jbeasts10]

Yes ,I have a boost fooler.(I made mine..air regulator set to 21psi)..I had the tranny built..upgraded internals/Billet triple Disk Converter..Transgo Tugger kit.
