Good question...I just bought my second TJ and fourth Jeep over the past 15 years. I'm keeping this one, as finally it's just a weekend toy! I'm looking to do a supercharger this fall/winter as well. I'm interested if anyone has input on your question as well. If you find any answers, please share! I'll let you know what, if anything I find out on the tuning.
