2014 Ram 1500 Crew Cab
I am very happy with this purchase. I have the 3.6L Pentastar engine. I changed tire size and needed to update so the speedometer and odometer would be correct. The tuner gives a nice increase in power and throttle response as well. I am running the 87 octane tune and have tried the 93 octane tune. It is a noticeable difference, but I did not want to spend the extra for fuel.
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.
