How much HP should a person expect to get by purchasing a U7146 Tuner for my 98 Cobra, 4.6L DOHC engine.

15-20 rwhp, 20 ft/lbs of torque.

Wow !, I was expecting a gain, but this 93 tune on the Predator has really woke up my Mustang Cobra. Eventually, I'll make it to the dyno shop and get it fine tuned. I did a pretty good job on my own on my previous Mustang with the Predator but I've read where some people are getting some really big gains by having a dyno shop fine tune it.

I wasn't aware there was a 93 octane tune. I have the 7146 and it just has 2 selections:
Diablo Tune
Factory HP tune

do I need to update it? W/ the Diablo Tune I'm not seeing much change. Car is stock w/ a magnapack catback.
