Installation and Overview on the Sprint Booster for the 5th Gen 4Runner
The 5th Gen 4Runner has a rather non-responsive skinny pedal.
When you begin to accelerate, the factory throttle response is minimal and for lack of better words, mushy. You really have to press down on the pedal to feel the 4Runner accelerate.
If you want to increase the response from the gas pedal, a throttle response controller will help.
By installing a throttle response controller, you can literally “control” the response you feel when pressing down on the gas pedal.
Sprint Booster Or Pedal Commander?
The Sprint Booster is similar to that of a previously reviewed Pedal Commander. Both units control the accelerators response but differ in a few ways.
The Sprint Booster (SB) has a smaller selector switch than the Pedal Commander (PC).
The PC comes with a detachable selector switch and the SB comes with 3M backing. If you wanted to make the SB detachable, however, buying some hook and loop backing to do it yourself would be pretty simple. The PC also has a few more settings than the SB.
What I like about the SB over the PC is that the unit is much smaller and more compact. The unit also doesn’t have any flashy colors on it so if you mount it on your dash somewhere, it may be less noticeable whereas the PC is larger, takes up more real estate, attaches to a big clip, and has bright yellow accents on it.
This is not going to be a Sprint Booster Vs. Pedal Commander article because they are very comparable and both units are worth the price and are far superior over driving stock.
It really comes down to where you want to mount the unit and how you intend on using it.
The Sprint Booster Is Impressive!
This is a quick overview of how to install, and use the Sprint Booster on the 5th Gen 4Runner.
After you install the Sprint Booster and take your truck for a test drive… WOW, prepare to be absolutely floored, pun intended.
The response you get from the Sprint Booster is unbelievable compared to stock. Having one of these installed is like driving a completely different vehicle.
It’s really amazing what these little units are able to accomplish.
We bought our Sprint Booster from Amazon, sold by Mini Mania which is ironically located about 30-min from our office.

Open Truck Door
Shut your truck off and leave your door open for 5 minutes. Just after the 4Runner shuts off, the CANBUS system diagnostics will run. To prevent check engine lights from triggering once you install the Sprint Booster, you want to give the system time to run a full diagnostic.
Choose the type of transmission
Locate the auto and manual transmission select tab on the side of the selector switch. On the right side of the selector, there is a slide switch where you can toggle to automatic or manual depending on your transmission.
Move the selector to the M/T position for vehicles equipped with a manual transmission or the A/T position for vehicles equipped with the automatic transmission.
For the 5th Gen 4Runner, you will leave the default selector and the A/T position.
Connect the selector switch
After you have selected automatic or manual transmission you can connect the selector switch to the actual Sprint Booster unit.
Locate the white socket on the sprint booster and take the selector switches connector and connect it to the Sprint Booster. If you do not connect the selector switch to the sprint booster, you will restore factory settings or otherwise known as a “valet mode“.
Again, before installing the Sprint Booster in your 4Runner, open your door and set your keys aside (away from the truck) for 10 minutes.
During this time the vehicle is checking the electronic systems of the car through the CANBUS system.
Installing the Sprint Booster
Locate the harness connector on the accelerator (skinny) pedal. Remove the harness connector from the pedal.
Connect a sprint booster to the pedal
Make sure that the Sprint Booster is properly aligned with the pedal connector during installation. Then connect the harness connector onto the Sprint Booster. Make sure all connections are firmly in place and run the harness connector from the Sprint Booster back up to the 4Runner’s dash.
Mounting the selector switch
Once you install the Sprint Booster you can attach the selector switch anywhere on the dashboard using the double-sided tape attached to the back of the switch.
Before attaching the selector switch to your dashboard clean your preferred area on the dashboard with a dry cloth. As a safety precaution make sure that the wire does not interfere with your foot, knee, or the accelerator pedal.
After testing the Sprint Boosters settings, I knew that the Sport setting set at 9 was where I would stay so leaving the Sprint Booster in one place was not a big deal to me. Once you find your settings, you don’t change them that much, at least I don’t anyways.
If you think you are going to play with the settings often, grab some hook and loop backing. With added hook and loop, you can pull the unit off frequently without wearing out a single double-sided 3m tape that the Sprint Booster comes with.
We had wires running from the fuse box to the center dash so we just connected our sprint booster to these wires.
Using the sprint booster selector switch
- Off: no light
- Sport: green light (improves the response up to 30%)
- Race: red light (improves response up to 60%)
To cycle through the modes, press the main Sprint Booster button one time. Pressing the button once will turn it on into sport mode and then into race mode and then one more time for off.
Each mode has nine selections. In sport mode (1-9), and in race mode (1-9).
Use the right arrow to increase the throttle response up to 9, and the left arrow to decrease response down to 1.
Press and hold the main button for three seconds to switch off the LED display, this is completely optional.
When you turn off the LED display, the arrow buttons are deactivated and the programs (1-9) cannot be changed. The programs you had selected or stored in memory. After you switch off the LED display, you will only have the LED light on (sport or race) that indicates the mode you are on.
