Yes, results will vary from brand to brand, model to model and even car to car within the same brand/model due to tuning, etc., Select 1-9 in SPORT mode (Green light) and 1-9 in RACE mode (Red light) with '1' being the least aggressive program and '9' the most aggressive one. Hey Garry glad you enjoy the feeling of your sprint booster. Not sure what your point is with your statement “My experience suggest you might have come to a different conclusion”. My conclusion is the sprint booster is just a voltage amplifier that fudges the accelerator pedal position. Are you disputing this? Even though some sprint booster vendors verify this in their documentation? Even when presented with the experimental data that I link to? How do you substantiate this? There is no way testing a vehicle with a sprint booster would make me think the sprint booster manufacturer’s own documentation is invalid or the results of the experiment I link to are invalid. That doesn’t mean you shouldn’t get a sprint booster. Many people like them. In fact I’d suggest that most people who’ve tried one like the result. People like the feel of the throttle response. Regardless of the fact that they can be perfectly replicated by pushing the pedal further, if you enjoy driving with a sprint booster then it’s a good thing. Try one out and see if you like it. However it is not a performance enhancement and won’t improve engine response or acceleration. Possible Safety Issue

Anyone that tunes cars or has a sound understanding of how a modern ecu works will understand what I’m saying here. So, what are we left with. Seems like both sides are happy pointing out their arguments for and against the use of such devices. I think, so long as people are aware of what the devices are and are not, yet they are happy that the new pedal response suits their driving style/requirements, then both sides should be able to live in harmony, you think…? The result, by product definition, adjusts the standard relationship between pedal position and engine speed control (throttle-position). I'm not going to drive your car. I have no interest in doing so and it's currently impossible anyway. The NHS has made it easier than ever for immunosuppressed people to get their boosters – they can now show they are eligible by providing either a letter from a GP team or specialist inviting them for a vaccine, a hospital or GP letter about their medication or treatment, or a prescription or medication box with their name and date on it.Pedal Commander has an eco mode, a city mode, and two sport modes and uses a “4 raise” and “-4 low” as their mode adjustments. This gives you 30+ modes. The moment you plug in your Sprint Booster V3, you'll experience an improvement and responsiveness to the touch of your accelerator. I've said before, the ECU controls the activation of the throttle body on a request from the pedal. No device inserted between the pedal and the ECU can change that. All a device can do is try to fool the ECU into believing the throttle pedal is pressed further than it is. Sprint Boosters gives drivers 36 acceleration levels, allowing you to find the perfect settings for different styles of driving.

I’ve used a sprint booster and so have experienced what it does to throttle response. However this article is mostly objective analysis based on the following:if you dip your foot to overtake you have to wait 1-1.5 seconds before any thing actually happens and when it does move the drive is spoilt and not nice atall. The delay time whilst accelerating in 3rd and 4th gear and the engine in the mid-range, is almost zero

The acceleration of modern cars is controlled by their ETC system (Electronic Throttle Control) – also known as drive-by-wire – which has the unfortunate outcome of delaying your throttle’s response time.As for SEMA - you do realise the last M stands for Market and that awards are judged by journalists? Another SEMA winner? The masters of marketing (also debunked many times by empirical testing and also the subject of much forum debate) K&N have multiple awards. Reprogramming the ecu is a better option, but more expensive, and for me I will wait unit its out of warranty eitherway. Although, each level does have about 10 increments and I found if I turn it right down on P1 it does help me in 3rd when accelerating. 3rd on my little rig tends to bog down and RPM’s drop quite fast so it does help accelerate a little smoother without me having to put my foot through the floor. My foot can also become more or less responsive depending on the signals my brain sends it. And I enjoy using my brain and body to do stuff since it’s the only way I have of experiencing the world. More than 470,000 people have come forward for a vaccine since the spring booster campaign got underway on Monday, with hundreds of thousands more booking in.
