Performance modifications on modern cars are so different from the cars I played with in the past.  You can still improve handling with different springs and sway bars, but engine and transmission tweaks rely more on technology than a turn of the screwdriver.  That fact doesn’t make it bad, just different.

Gone are the days when you flipped over the air cleaner lid and changed the jets in the carburetor.  Tuning today’s cars require a computer programming degree, or a reputable company that does the work for you.

First Step: Identify the Issue

Since buying my Camaro two months ago, I’ve been getting to know the car and the opportunities for improvement.  Overall, I am really pleased with the engine performance and chassis dynamics.  Acceleration from a dead stop could be better.  Once the car is rolling, the turbo takes over and is rather thrilling to experience.

The initial application of the throttle has a slight lag before engine speed increases.  The “gas pedal” in most cars now are electronic throttle controllers, so there is no mechanical linkage from the pedal to the carburetor/throttle body.  It is essentially a switch that sends a signal to the ECU (electronic control unit or engine control unit).  My guess is the programmed throttle lag is a way for the manufacturers to build in a buffer to protect inexperienced drivers.

Sadly, it gives you the impression that the engine lacks power at low speeds.

The Solution

Luckily, the aftermarket addresses this performance shortcoming.  In fact, there are many companies that offer a product to improve throttle response.  The solution is to introduce a module that fits between the gas pedal and the ECU.   This module modifies the signal input to the ECU, allowing the user to change the sensitivity of the pedal.

After some research, I found several throttle controllers on the market.  They include names like Pedal Commander, Hike It, PedalMonster and Roar Pedal.  They range in price from $159 – 300, and offer everything from a rotary tuning dial to a smartphone app to change pedal sensitivity.

Based on a combination of product reviews and price, I chose the Roar Pedal (bluetooth model) for $159.  I ordered it directly from the company and it arrived within days.  It came with a 30 day full refund option and a 3 year all-inclusive warranty.

Easy Installation

Installation could not be easier.  You unplug the original cable connection at the accelerator pedal, then plug the Roar Pedal module into the pedal’s connector.  The vehicle’s throttle wire is then plugged into the Roar Pedal module, and the wires tuck under the carpet to keep them out of harm’s way.
