I have heard of some manipulating the fuel map to make the burn leaner. when i first bought the car, i thought that i could run lean by easing up on the gas, but that's only true in honda engines, not the L91. without modification i get constant 14.3:1 burn at all throttle ranges. i have heard about swaping the MAP sensor to move the fuel map, but i'll have to wait until i can get my hands on a Chilton's manual. i don't even know where the sensor is. the easiest thing i can do is get a K&N air filter. Perhaps that's the cheapest way to get a gain, right now.
