What I'm really curious to see, is how the fuel mileage on the track does
next track day after running it with a leaner (13:1 A/F target) vs the stock
"pour in the fuel" 10.5-11:1 settings. About all it does is 6-7 mpg (last
time around anyway).
During the 2nd day last time, it was A-B-A-B groups all day. I went through
2 tanks.
Guys behind me were probably getting an extra 10 hp just from my fuel
infested exhaust :)
