hey guys just wondering what mileage ppl are getting for their full exhausts with a map on their 09 r1's
i have a full leo vince evo II system with the leo vince FAST II fuel unit. it has a custom map done @ leo vince and showing 156horsepower.
my last avg mpg showed 25.7, is it really that low with a full system/custom map?????
