Just bought a 06 CTD. I know it has a programmer, exhaust, and air intake. Wow does it run. Question bought it used and not sure but is there a way to know what programmer I have? Update from another post of mine the shake was from a torque converter and input shaft. Didn't buy that truck thank goddness.

 

post a photo of the programmer.. I'm sure someone will ID it.

 

Where do I look? Didn't see anything that stood out under hood.

 

If its a programmer then there won't be anything noticeable. A programmer is plugged into the truck through the diagnostic connector to reprogram the trucks computer then removed.

 

Ah... I thought you had the programmer in hand.

My truck was programmed when I purchased it. I insisted the dealer re-flash the engine computer to return it to factory defaults. Unless you have the programmer to adjust the settings, I'd recommend you do the same.
