I am driving myself crazy trying to tune my car. A/F ratios are so random I can't control them. One click on the fuel slider and it will go from 10's to 12's. And then if I'm crusing and I hit the gas in 5th gear the car runs very lean even though it was just running in the 10s at that rpm range on my 3rd gear pull. When I got home I looked at injector duty and at some points it was in the 90's. I have 680's, how could this be. Also, last time I tried to tune I didn't even touch fuel and it stayed in the 10's the whole time. Today, I've been adding fuel just to keep it from running lean. Any ideas on this? I'm going crazy.
