The design of the Sprint Booster allows for its easy installation in all models, without the need to cut any wires (plug n’ play) or intervene in the automobile’s electronics (it does not affect other systems such as electronic injection, ABS, etc.). 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.

Another point worth considering is if the sprint booster also provides some signal conditioning which would either benefit range or linearity of the throttle pedal position signal. One of the previous posters appears to be able to get more power when flat out up a hill with the sprint booster fitted. Assuming that this is true (and I have no reason to believe it isn’t) and there aren’t any other environmental factors (air temperature, altitude, humidity etc.) then we can only assume that the sprint booster is conditioning the signal and providing a greater maximum range output.But I will think more about buying one as don’t if this is how they work, I would assume the good ones do. I would rather one that also took in speed and brake inputs, perhaps it could be done with an extra connection to the programming port.

Even in an application where you need full throttle immediately all the time, the driver will anticipate the limit of when full throttle can be applied based on the characteristics of the vehicle. So apart from unanticipated full throttle requirements, I don’t think you will see a 0.1 second advantage coming out of every corner. But a sprint booster could still provide a marginal advantage I suppose, at the expense of poorer throttle accuracy which could be a disadvantage at different parts of a corner or some other scenarios. The accelerator pedal transducer is a potentiometer or hall effect sensor. It is not an intelligent device. There are no time delays or filtering performed within the accelerator pedal transducer. The filtering is done in the ECU. Why? Why would the vehicle manufacturer add complexity, expense and points of failure within the accelerator pedal transducer when that capability is already there in the ECU? Add a few lines of code and it’s done in the ECU without any extra hardware, cost or potential points of failure.Anecdotal evidence from people who have tried sprint boosters does not invalidate this article. This article is consistent with technical information provided by sprint booster manufacturers. I’m certain that the manufacturers themselves understand how their own product works. Design Compromise The delay time whilst accelerating in 3rd and 4th gear and the engine in the mid-range, is almost zero I want to understand the physical process behind the delay. How is there a delay through a resistor and how does a sprint booster circumvent that delay? Or, if the delay is introduced downstream of the throttle pedal position sensor, how does the sprint booster circumvent that delay?

The characteristics of the adjusted pedal can, in some cases, be easy to duplicate by pressing or releasing the standard pedal at a different rate. We found this video on YouTube and felt it was a fair and unbiasted reveiw of "Sprint Booster vs Pedal Commander vs BMS Pedal vs Pedal Box vs Injen Pedal Pro vs China vs Hike It." Courtesy of Master Chief. 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…? Some of the people who have contributed to this forum have lost sight of the fact that you have voluntarily taken the time to research this product and put forward a credible point of view with good intentions and in good faith. I for one appreciate the efforts of people like you who take the time to provide an objective perspective. No offense to the supporters of the sprint booster product. Everyone is entitled to an opinion. As Joe said; for those that own the product and are happy with it; that’s great, happy days – drive on. And the strangest thing is that I noticed a bit of an increase in MPG. Apparently whatever I was doing to keep the car moving as I wanted it to used more gas than what I can do now with this thing attached. And I don’t even care about MPG.Sprint Booster is a small, lightweight device that is barely noticeable when installed. Mount it anywhere for easy access to it. And to be clear, Sprint Boosters DO NO give you more horse-power. Sprint Boosters make your accelerator more responsive by drastically improving your throttle response time and giving you INSTANT GO POWER. Sprint Boosters gives drivers 36 acceleration levels, allowing you to find the perfect settings for different styles of driving.
