As 3.6 does all it can do for editing and scanning regarding the vehicles ive licensed, how much of a gain and benefit will 4.0 provide over 3.6 for what I've already applied credits to? Anything taken away with 4.0 that 3.6 supports?
Main vehicles id like to know direct impacts to are:
2008 & 2009 caliber srt4
2006 h3
2008 Colorado 2.9l
