I changed my blower pulley a while back to the 3.2" and have never really watched my mileage. This last week I've been doing a lot of around town driving and it sure seems like my gas mileage is better than when the car was new. I have no mileage numbers to justify my suspicions but it sure looks as if my gas gauge moves slower. Has anyone else experienced this effect? Better mileage and more power at the same time. If it's correct, it's FANTASTIC!!
