I'd consider making your AFR target's a bit richer at 100kpa, 12.8 is a bit safer. It looks like you have a lot of fine tuning to do under load, I'm seeing swings of .5 afr up and down. Try to get it within a .2-.3 window from your target AFR more consistently.

EDIT: I looked at your VE map, it has the topography of the Sierra Mountains...start smoothing out the map. Search around for a spreadsheet that helps interpolate the numbers quickly.

Thanks for looking i found an excell sheet that can do that here on the forum to interpolate the data. I am going to hit the track again this afternoon and work on getting the AFR targets closer to +-.3. Also i was told by Hustler to shoot for 13.1 at WOT above 4500 for most power and while i agree 12.8 is safer i have got the impression that 13.1 if fairly safe as well while making the most i can.
