Just a heads up to guys like me who like to research everything they want to put on their car. If you go with a Bama Performance tune and live in a state where they do emission testing during inspection - this tune will cause you to FAIL emissions tests as the O2 sensor, O2 Heater Sensor, and Catalyst Sensors will not go "Ready". From Bama Performance's own website: "Bama Tunes will not affect your vehicles emissions or smog testing." - this is why I went with them so I did not have to mess with tunes just to get my car inspected. After several back and forth emails and phone calls with Bama I basically got "of course our tunes affect these sensors - that is how we improve performance..." and you are on your own regardless what our website states. Just know if you buy a tune from them you WILL have to return your car back to stock to pass an emissions test if your state does this. Sure wish they would be more honest and up front about this instead of telling you AFTER you spent the $400 for a tuner and tune.
