so... i've finally ordered my exhaust, and I'm looking into intake now... well actually I've already got that figured out...

I have a JLT II v6 intake system waiting to be bolted on... but I need a tuner!

SO! here's my question... I've been noticing some write-ups every once in a while on this forum site about xcal III bugging out?

I was wondering, how many of you run the xcal III in your v6 mustang? and how many run xcal II?

B@M@chips have some sort of special in favor of the xcal III right now...
