I have noticed a lot more power with my mods, but my gas milage has really dropped. I have lost 6 mpg. I have a set of Cobra Pipes This winter I cut the baffles in half and drilled 3 1/2 holes in each one. I also put on a S&S intake. I have the FI2000 set at 2 2 2. It sounds great and runs great at this setting, but does anyone know which one of the three adjustments would control the fuel mileage. I must be running rich. I have seen the forums and they talk about 1 2 2. But the motor idles a little rough at 1 and smooth at 2. Any thought on this would be greatly appreciated especially with the high gas prices.
