No other tuners installed, Harleys run lean stock so any modes done after stock will most likely make it run even leaner.
Thats why I was thinking someone might, or should have, added a tuner when the mods were done. I can't even add a hi flow a/c on mine without changing the AFR or it will be way too lean. I need to do something soon, cause it's HOT in Dallas already. 97* tomorrow thru the weekend. Yuck!!!!
