I have two Chargers one is a 2012 sxt plus and a 2015 Rallye. Now from what I have read is the SRT pages will not show up on my 2015 because it's an 8 speed? Next big question do I need to buy 2 tazers one for each car? Next does it work like claimed on the 3.6 and unlock all the SRT goodies? has any one had there pcm go bad because of it?
