If I had to do it all over again, I would go with the 93 Perf, 93 Race, and 87 Perf.tune's. I didnt like the 93 Torque as much as the 93 Perf, and by judging by the opinions on this forum, 93 Race seems like a good one too.

I have an even better idea...take ur XCal to a local mustang performance shop and get a couple of custom tunes and go from there...
