Well I have a SCT XCal3 in my powerstroke with custom tunes on it but lets face it at close to 5 bucks a gallon my truck only moves 30 or 40 miles a week. I saw in a post the other day about one of the tuners having the 93 octane tune for $50 i was just thinking about giving it a try for a little bit in the stang. If its not a name that can put in a post or whatever I welcome a PM with any info on who has what. I just want to run it for a while and see if it makes as big of a difference as has been said. I dont know how long i can handle the stroke having 150hp and 300lb ft taken away from it.
