The bottom line is that all the OEM manufacturers of factory EFI equipped vehicles have done a very good job of compromising power, economy, reliability and emissions concerns. Any gains you will get in one area will be hard won and will negatively affect the others.

I have considerable experience in tuning my engines for economy so I'd like to think that I know what I'm talking about. I also have a 91 Sprint and a 91 Miata in my stable. They work so well from factory that I wouldn't even consider modifying them. My Sprint is a $900 beater with almost 300,000 km on the clock. It averages 58 mpg Imperial in summer, 56 in winter. I don't know how I could improve on that.


Well, I guess I better quit trying to Ecomod my Metro entirely. While I'm at it, I can quit all the forums and just rely on the auto manufacturers to meet my needs. Thanks for the support. Remember - never question anything and never strive to do better than others have done. Cheers.
