Have a 2006 Mustang GT auto. Looking to get either a SCT XCALIBRATOR 3 or a Fuego Flash Tuner. Which would be the better choice?

 

Depending on where you live and how far you are going to mod the car I would get whatever your local tuner uses. That way if you need to get a dyno tuner later for a supercharger or nitrous etc... he can use the tuner that you buy.

Otherwise SCT is better then that GMS bullshit.

 

sct is used by most dyno shops and is a very good tuner. i've never heard of a fuego tuner. get the xcal 3.

 

Bump for SCT
