Review on Enhance Your Honda Civic (2012-2015) Performance with Pedal Commander PC21 - Throttle Response Controller for Base, EX, EX-L, HF, LX, SE, Si & All Other Models (1.4L 1.5L 1.6L 1.8L 2.2L 2.4L) by Demarco Vonk

Good. So there are two types of people talking about this product online. Those who appreciate it and those who have never used it. I read on the forums what a waste of money $300 is. Let me explain. This product does not support HP. It won't improve your top speed and won't make much of a difference in the higher rpm range. But at low revs and out of the corner you'll notice incredible throttle response. It will take some getting used to at the highest settings. It basically amplifies the input from your foot. In sport mode plus a barley touching the gas pedal causes the throttle to open fully. But in Eco mode the pedal to the floor with the throttle half open. I installed a cold Cat Back air intake and exhaust the same day and didn't "feel" the increase in response that I feel with the Pedal Commander. And it was more like a $1,000 upgrade. In addition, this device connects directly to the accelerator pedal and not to the computer. So you can still vote on top of that. It works with everything you do.
