I would suggest, if possible, ride in two MMs, one with a Lidio and one with a DR tune to see which you like best. Then take the car to good dyno place and have it dialed in. That is what I did and it really made a world of difference. The out of box tune I had was making no extra power, confirmed by dyno. I went from 242RWHP to 273RWHP after the dyno tune. I picked up 50 hp in the mid range. I will qualify this as the tuner said he rarely sees a tune make that dramatic a difference. My tuner also completely changed the tranny tune as I did not like the out of box schedule.
