Talked to another Burb owner here in NC. He said he was using underdrive pulleys which helped to improve his mileage and HP. Just wondering if anybody else is using them and what results they are getting. Recommend or not ?

Thanks

Steve

Wouldn't recommend them at all. Sames some gas by slowing down accessories but it lowers your accessories ratings/volume as well....which is not so good. Just my 2 1/2 cents.
