ive searched and seen that some are getting high 20s-30mpg, while hitting boost daily. how are you guys doing that? seems my miles suck..im probably getting low 20s per gallon, which is with some boost, trying to stay in vacuum. 20 bucks of 91 at 3.70 per gallon literally lasted a day, about 100 miles of city and freeway driving. any tricks besides staying out of boost?
