sniper or xcal2?

i am in nyc, and need a tune! so i called up mustang magic in LI and asked them about installing my pulleys, c&l cold air, and dyno tuning my car. they said they would do an xcal2 tune if i already have the tuner, but they said that they tune with the sniper, since it has more options, and they have had better luck making more power with it. should i have them sniper my car, or should i buy and xcal2 and bring it in and have them do it??

thats what i thought, but everyone around here that i have talked to says mustangmagic, and thats what they tune with... heres a couple links...

well i got my appointment for mustang magic to tune it. on tuesday they are going to install the steeda pulleys, c&l CAI, and maybe my line locks if there is time. it is going to be sniper tuned. i cant wait to see what my baby does on the dyno, and then ill slap up the results.
