Let me clarify. Are the tunes the same between the GT and the Mach?

FBGI0 covers 2001.5 - 2004 Mustangs V6 GT Mach-1 Cobra Manual and Automatics

No, the tunes are not the same. Regardless you will have to dial it in.

best bet for a mach though is to become a premium member as high compression 4v's can be pesky with timing and dashpot.

So another crazy question. im used to tuning the GUFB. Do the 03 04 cars have factory wideband o2s or are they narrow band?

So the mach i have is a 03 with 97 Mark VIII shortblock fresh built and set of 04 9 thread heads. The only thing ill really need to tune for is the 90mm lightning maf and longtube headers. Would i better off getting a SCT handheld or using my QH?

sct is garbage for the older vehicles. QH is the only way to go.

yeah you definitely need a remote tune
