I'm looking into getting the SCT Excal II. I have only added bassani o/r x pipe,tunable induction cold air, and getting ready to install bassani headers. I'm probably going to get the tuner from JMS chip...I've heard a lot of good things about them. I don't have a place even close that does dyno tuning. I will have them make a custom mail order tune for my Saleen. My question is...Can I datalog with the SCT once I get it and send it back to JMS to fine tune it after that or do I still have to get it dynoed somewhere?
