Hi guys, recently purchased this 06, it has a airaid filter assembly, mbrp 4" exhaust (no cat) just had tranny repaired, now I know has a after market TC and shift kit, my question is, how can I find out if it has a tuner , chip , modified flash file or any of those mods, where do I look...thanks

 

My truck will throw a 0602 code if there is a program in it. I'm not sure on the newer trucks.

 

you probly wont know until you try to throw a programmer on it. if there is a chip look under the hood, it would likely to be plugd into some sensors(map-pressure sensor ect..)
