I have a 2017 Mustang GT/CS 5.0 Automatic. I've purchased and installed a Roush CIA and a Borla Racing Exhaust prior to purchasing and installing the Pedal Commander. While those upgrades brought some life to the engine and added a great deal of exhaust acoustics...the Pedal Commander made the biggest difference BY FAR! I’ve yet to even really do much in the Sport+ mode. Sport has thrown my head back and ripped the rubber every time! This thing is just flat out awesome! Literally took 5 minutes to install. Where/if you decide to mount it may take a little longer. I just ran mine through the steering column trim and then looped it around the top of the steering column trim between the steering wheel and the instrument cluster. Super easy, super accessible, and easily removed when taking it in for maintenance. At a price tag just over $250 it’s a no brainer, wish I had made the purchase sooner.---UPDATE 08/27/2019---I have since gotten my Mustang Supercharged with the Roush Phase 3 kit that provides 727hp. After picking it up at the dealership I left the pedal commander off to see if I'd still need it...man do I!!! Don't get me wrong, the supercharger could be felt around 2500-3000RPM, but the pedal commander gets me there so much faster than the Roush flash does with the supercharger. I have noticed that when I drop the pedal to the floor it has some misfires but I think that may be due to 93 octane with ethanol. I'm looking for an ethanol-free gas station to rule that out. I still think this was the best bang for my buck by far!
