I received my SCT 9100 from Steeda today. They were supposed to have programmed it with two different programs...one for a 87 octane and one for 94 octane. It only came with the 94 octane program...I will have to call them tomorrow and tell them...

Anyways, I flashed my 03 GT with the 94 octane program and it runs quite nicely...alot smoother. The one problem I am having is that my speedo now is way out. It says that I am going about 8 to 10 mph slower than I really am. I am thinking that the program that I received is for a car with a 4.10 ring and pinion? Would a slow speedo be a sign of that? Any thoughts?

I believe the higher your gear ratio, the higher the speedo reads. So... if you have 3.73 and it was flashed for 4.10's, yes it would read low.
