Default Re: Gas Mileage

mmm.. when I run the 93 tune on the highway I geta bout 27 to 28 IF, capitol IF, I drive like a human, which doesn't happen very often. Around town, I run a lightened race tune. I get about 21mpg. Right now I'm looking for either a vacuum or boost leak as it's dropped to 17mpg in the city.

When I run long trips, I put in a set of plugs gapped at .40, when I run the track, I replace them with a set gapped at .35. When I dyno'd this last at Rage-Tek, it seemed to perform better, top end, with the slightly narrower gap.
