MPG

[lukecp]

I am tring to increase the MPG on my truck. I have a mild 350 in it, with a 204/214 cam, flattop pistons, Edelbrock Performer intake, HEI, headers, and a Edelbrock 1406 carb. This summer i got 13.1 MPG around town. It dropped to 12.25 during December-January, with my Qjet still on it both times. Anyway, i went ahead and bought a Edelbrock 1406 for it and put it on. Out of the box, it ran OK, but it was a little lean under light acceleration. So, i bought a calibration kit for it. I stepped it up a little in the "power" mode, and only changed the metering rods, to a #1456 rod (.073x.047). I kept the stock metering rod springs in it. My power increased ALOT, but my gas mileage dropped to 11.6. Should i try to put the stock metering rods back in, and add heavier springs instead?
