I finally got around to logging a pull from the start of second to about end of fourth. I have been having bad results in the last 1/8 of the 1/4 mile. I see a knock spike consistantly at about 6800 RPM. Is there something I should look at in my cal to fix that? Thanks

afr's at 11.9 around there as your air temp goes up. and it looks like it's at pretty high rpm...maybe richen up the top a bit?
