Colder plugs are supposed reduce detonation(?) and thus allow more power to be made???
Mike said something about the fuel pump increased pressure allowed for lower injector duty cycles...
I was just throwing those things around as possible discussion points as to whether they or the weather might impact dyno numbers.

I devoured many Audis, Porsches, a Lotus and a race car or two at Thunderhill, and am still hungry. I want my DMSes back from Oh-Canada...  |

Your tire: 235/40/17 = 24.4" diameter or 225/45/17 = 25.0" diameter
Matt's tire: 245/40/18 = 25.7" diameter
Matt's car probably makes more hp and torque than yours based on the tire gearing difference alone, nevermind the loss from turning 28lb 18" wheels.
