a/f question for you guys... Hey. I have the predator, and I tuned my a/f to 12.8:1 on a dyno, and with atap, I am supposedly running too rich .950, and .930 on my O2 readings. I guess I should be at .890? Any opinions? Thanks.

Re: a/f question for you guys... All the curves I have seen show 12.6-12.8 as
the peak power mixture. Lots of people keep
saying to lean it out but I've never seen any
hard info to make me believe this motor is
that different. Yeah, it's "rich", surely
compared to stoich. But hey, only for 10-15
seconds at a time, right?
You can mess it around a bit and see whether
you like leaner, better... and how much. Data
would be interesting either way.

Re: a/f question for you guys... any other opinions? I may mess with it at the track this weekend. I get 250 miles to the tank with my a/f around .890, and at .950(Current) I get around 200miles to the tank, 215 maybe (Both are in the city)
