knocking badly!

[4seasons69]

ok so i'm still having issues since having my car tuned. I fixed all my ect wiring it reads just fine, reloaded my tune in and the car is still knocking bad like 22 counts. my wide band reads 10:1, afr est is at 9:1, boost est is right on. and my ltft lo is at -12.

I haven't changed or messed with anything on the car since having it tuned except fixing the ect wires.

now while at work tonight I was able to do a boost leak test up to 25 psi and only found one small leak at a vacuum port I have capped. (i'm going to put a new vac cap on when I get home)

now could the knock and everything being off be from this one little boost leak?

any help is apreciated!
