The one on ebay for $209 and the one on autoenginuity's site for $249 are the same basic version, for either of these to do the advanced testing on a powerstroke you need the Ford Enhanced Package for $149, that will unlock the functionality of the software you would buy from ebay or the AE website.I'm looking at purchasing an autoenginuity, i saw them on both ebay and autoenginuity's website. So from what i read the one on ebay is just basic. Is there a big differance between the two?
