I started looking into tuners for my car. I have a 2010 RT 6spd with 20s and the 392 rear axle. I really liked the ides of the flexabilty of the trinity tuners and being able to perform adjustments to suit my needs. My question, for now , does the display for the trinty need to be plugged in and displayed all the time, for like the others, is it a plug in, download and leave in the garage for the next mod. Thanks.
