Well I don't have tuning software and don't plan to go buy any. Thus I'll give you an opinion - not a recommendation. Go with the software you think you can leverage with any experts you'd like to dialogue with, have take a look at your data log - etc. For instance if you went with EFI Live you could bounce data, info back and forth with Mike at Vengeance ( IIRC you worked with Vengeance for your original tune ). Or maybe SCT since Ted at Jannetty's works with many people long distance. Or HP tuners if you know an expert there. Then over time you will learn and gain confidence to go it alone but until then it would be nice to have a relationship you could leverage.
