Just a heads up, couple of my friends (one with an LB7 other with LLY) both had major issues with their Edges, ended up needing new PCMs but they were using them for the tunes also not just gauges. The one with the LLY had an LB7 first and it was fine with the Edge until it met a tree at speed(the DD ended up drinking more than he did :fp: ) and a 3rd friend with Cummins had Edge Comp Box and loved it never had any issues.
