I have a 2009 Mustang the base v6 model and I was just wondering what performance chips would be good to use in my car. I don't really know anything barely about cars so I mistakenly bought a SLR Motorsports chip before I looked at the reviews so I don't dare put it in my car now and I was just wondering if I could get some input from people that already have some chips in their car to see what i can do... Or any parts that can help me with gas mileage or Hp... either will work lol...

 

SCT and Diablosport are popular hand held tuners. They both will give you better HP and gas mileage. If you were looking at either one of those I would also buy a CAI as well to free up even more hp.
