My mpg has actually gotten better on the hwy by about 2mpg. On the city side just depends on how hard I accel and run the car. Normally I'm around 18-9 mpg city.
NOW - new info coming hopefully soon on a FI kit from a specific company that is doing reversed vortech superchargers and a turbocharged kit. Not passing any word other than that until I get the okay from some people.
