Well made but only worth it for specialized applications
I have a stock 2012 Challenger SRT running the 93 Octane tune. Not enough difference to justify the price. The torque management is definitely less but I am not so sure that was really worth it. All it does is have a jarring shift. Seems bad for the trans. Not appropriate for street driving. What I really wanted to fix was the bogged down throttle response. This didn't seem to do anything. It did turn of MDS. Well made and easy to use. Seems better for the strip or serious mods.
