So I have been looking at getting a programmer for my truck. I just want the basic 3 tunes, on the fly, an somethin to monitor gauges. Did some research an decided efi live is the way to go. Saw a package deal on a site for efi live an cts2 monitor. Pretty sure this will be the route I'll be taking. Guess my real question is will I be able to switch between tunes on the insight cts2? 2014 duramax 2500 LML. I apologize if this is a dumb question. I have searched everywhere for an answer. Everything I find is from like 5 years ago. Is this not the way to go with tuning my LML?
