So what if the exhaust gas smells different.
A "street tune" is a race car thats a "safe tune" to run around on tha street. A "street tune" just makes it safe to run pump gas (and 110 isnt pump gas! any thing over 93-95 is considered race fuel) so that air to fuel is leaned out to a danger point in high rpms. A "street tune" should be renamed to a "safe tune"
