(sorry hosting for bunch of other pics of airboy settings and 3rd gear pulls went down)

More on car here:

I ran out of road and stopped at 6.2k RPM. My AFRs used to be around 10.9~11.2 but recently since I cleaned my MAF and filter from oil/dirt it flows more. 11.5afrs will be too aggressive in the summer. I hit 4.6MAFv around 6k RPM, went above 3.0g/rev load, it's definitely making good power.
