That's the problem with talking about MPG. It's kind of meaningless unless you know what the starting MPG was. If base mpg was 10, 4-5 is huge. If it was 70, less huge. Sorry - pet peeve.

The only person I know of who's done any systematic testing of inflation vs. tire pressure is krousdb. But I forget what he found. I'll go poke him and see if he has any info.

I've already bypassed the A/C compressor and I'm thinking of doing the same for the power steering pump. My past has been building cars that go fast, so I'm thinking along the lines of parasitic loss elimination to free up some hp, which should translate into better mileage, correct?
See this thread for some info. Careful, of course, as the power steering rack has a different ratio compared to a manual rack. (IE it's harder to steer a de-powered setup than a manual one.)
