Re: Running lean with poor gas mileage
A thought just occurred to me. I didn't know about smog block off plates but I recently started looking into them (probably get some when I get a PC). As I understand they eliminate the emissions control stuff that pumps air into the exhaust to burn unspent fuel in order to meet standards, so if you're tuning the bike this can cause a misreading in the a/f ratio.
You guys think its possible that the shop was still getting a lean reading after adjusting the ecu even though I'm getting terrible mpg because of this?
Also, is the PCIII my only option for the 2004 r6?
