99-04 Mustang GT (SCT ,Diablosport, Sniper)??

Hi,

I have 1999 mustang gt and I am looking to tune it. Currently it has CAI, LT headers, exhaust system and throttle body. I bought HP Tuners but I found that it doesn’t work on my car. But It is fine, I used the hp tuner to tune other cars and I like it. Does anyone have experiance with softwares for 99-04 mustangs? I am considering (SCT advantage III, Diablo Sport, Sniper commando). Which one is the best? I mean that allows me to access more parameters because I am planing to go FI with my mustang. Is there any recommendation?

Thank you

I don't have any personal experience with it, but I'm pretty sure SCT is the most popular for that era Mustang.
