Finally got some knock!!!

[Cakes]

I know it may sound stupid but ever since I installed my Scanmaster I have gotten NO knock from it. Today I decided to up the boost and I finally got some knock. Before at the top of 3rd gear I was always getting o2s around 810-840 with 0.0 knock. Today at the same time (top of 3rd) I got 02s around 760 and knock of 1.4 ONly once did I get knock of 4.1 and my o2s were 741. I know thats lean but where should I go from here? Since my 02s are so different everytime,should I replace the O2? Should I lower boost? Thanks for your help!

up the fuel pressure to get the 02's back up around 800 that way you have some lea way for cool nights or whatever that may lean it out a lil.
