From LS1fans.com worked great with the efilive tune I had. This is for the 03+ trucks. Sold truck so I removed upgraded parts. Only used for a few months. Sorry but the pcm wires were cut during removal (thanks bro). They were a little short anyways. I hear you can use the pins from a rear O2 sensor. If you like, I think I have one around that I can throw in as well. How about $65 shipped? Thanks.
