hey matt
just noticed that a guy i was talking to on the teamswift.net forum lives in SLC too.
he just ordered a custom ground cam for his 99 metro 1.0 from a machinist who's also a teamswift member. it's ground specifically to increase fuel economy - the machinist makes several different profiles (turbo 1.0, performance 1.0 n.a., and economy 1.0).
i was thinking of doing the same thing next spring/summer, but i'll gladly let this guy do the research for me
he's scangauge equipped, understands the importance of controlled testing and said he'd get back to me with the results once he's got it set up.
