Chico, The car was not lightened, when I ran my 12.95 it weighed 3555 with me in the car.
As for the reason why it was lean down low is because I was sitting there at a certain rpm then at that point the computer just set the A/F ratio to the lean side, then once I nailed it, it went rich. This is what my dyno man told me, not sure if thats true or not.
