I need to know which tuner would be the best for a 2000 GT.

 

I can only speak of what I have used: I have used HyperTech and thought they were o.k., I am currently using SCT in my 03 Mach1 and I have been very happy with it. Feels good based on the seat of the pants dyno and was very easy to use.

 

I also bought an SCT yesterday, after owning others. Everyone has their own favorites, and will probably tell you something different. But the SCT has proven to be a GREAT tool for my tuning needs.

 

sct is made for fords. the program is specifically for fords, were diablo is for chevy. and others are universal
