2007 pontiac g6 GT 3.9L
As the topic Says i have an 07 Pontiac G6 GT 3.9L. Its a 6 speed manual its running about 240hp but i want some more what are somethings i can do to give it some more power without losing the gas mileage.
hand held tuner, anything engine wise you do to give it power is going to effect your gas mileage...get a cold air intake and a performance exhaust to start though, you need to clean up the air flow before you start working on the engine, I'm assuming you have a drive by wire instead of a throttle spring as most 05's and after do, BBK makes a throttle body to help with reaction time and racing gears to start, 4:10s.
