Alright so I just found a tuner on here for a good deal. It's an Xcal2. It has a 91 octane tune on it for an 06 GT auto. What would I have to do to get it to work for my car? I'd have to get a new tune correct? Would I have to do an email can tune, or could I go to the performance shop down the road and have them throw a tune on it for me? I'm really new to the tuning thing, and I'd really appreciate the help. What kind of tunes should I get? What kind of difference does it make the car? Need responses asap cuz I need to buy it before someone else does!!!!!!

Thanks

 

ok there are various options and this is just
one.

personally knowing what i know, i would mail
the xcal to brenspeed and pay him to set up
the device for your pcm strategy and to load
the tune(s) you want ie. 91

make sure the xcal is UNLOCKED from the previous
car before purchasing!

 

If its locked, is there any way to unlock it?

 

first way is to return the original car to the
stock tune

second way is to send the xcal either to sn sct dealer
or sct themselves

to my knowledge, there is no other way
