Will keep ya posted on the results.

After alot of research, experimenting and rescaling the MAF, I think I finally scaled my MAF correctly to reasonable limits. Turns out the MAF scales on the OFT stage 2 v2.076 tunes were too aggressive so I used a near-OEM MAF scale which seem to the trick with my stock airbox with a perrin inlet tube/drop-in filter.
Here's my log (warning: it's huge, I jammed my 3rd gear pulls, cruise, and some spirited driving into one big log)

Note: The first and third sections are a bunch of WOT 3rd gear pulls. The last two sections was me trying to get some positive FLKC to recover my IAM by doing a lot of low throttle pulls. My IAM is essentially a wild rollercoaster ride
So I think it's safe to say that OFT tunes are too aggressive for catted headers? I get consistent knock corrections around 3000 to 5000 rpm. I applied Wayno's base timing B, and knock correction A and AVCS tables already.
Safe to say my next step is to start removing timing at those rpm ranges using kodename47's knock correction tools?
