I have a SCT X3 tuner lined up and was wondering what info about my 09 GT I would need when getting a custom tune from say brenspeed? Also where I would find the info for it as well, Thanks

 

Just ordered mine from Bama, but most want the same info (available on their websites)

engine
axle code
list of performance mods already installed
calibration code
transmission
tire size (complete)

then select the three tunes you want

 

Go on bamatune and over there they show a list of what they need to know to give you a custom tune. You don't need to order anything before you do that either.

 

awesome that's what I was looking for
