Thanks I think I'm going to look into the one that does not tap the wire. I'm chicken #$%t since I still have one more year of warranty. I was looking at the Edge Ez when I got my new TDR and read the add for it. My nephew had some Banks accessories on his PST Excursion before he switched to Bully Dog due to some contractual reasons. He liked the comp, exhaust, and even saved the Banks unused guages and is giving them to me all I have to do is get the sending units! What is the smoke like?
