Diegokid If your run FI and lean the crap out of it. This will get you into the 20's. Remove the windshield and go with a helmet should be go for another 4-5 mpg. Coast down alot of hills for the differents. Get out and push up hill.
Put the smallest cam you can find in your motor, lower the compression. That's about it. GOOD LUCK. Rick L.
