Mike may be able to speak to this since his car is now lean burn equipped.

The aeromods have enabled me to operate in lean burn to much higher speeds than a stock VX which, from what I've heard, drops out of lean burn at speeds above 65mph. So far, I've run in lean burn on a level highway at speeds up to 91mph. Based on the injector pulsewidth needed to maintain that speed, I should be able to to reach close to 100 mph before dropping out of lean burn.
