I was astonished by the power the Pedal Commander unleashed on my Kia Optima. Literally the best $300 I've ever spent. The results are both immediate and mind-blowing to say the least, I would definitely recommend buying this product if you're looking for better throttle response and more hp and torque from your vehicle. 5 star rating most definetly thank you Pedal Commander. Everyday I'm sporting my new Pedal Commander Mask and Key Chain. Promoting to the fullest!!!!
