Lot of folks have said they don't want to purchase a trinity because they don't want to have to leave it in the vehicle. The Trinity tuner does NOT have to be left in the vehicle to retain programming. You have that option with the Trinity. But you also can program the pcm, and put the tuner back in your house.
