Transform your vehicle's performance with the Sprint Booster, a state-of-the-art electronic device designed to deliver swift and instantaneous acceleration, effectively eliminating any delays. Featuring a convenient dash-mounted selectable switch, you can effortlessly switch between stock, moderate, and aggressive acceleration modes by simply pressing an LED button.
In the era of modern automobiles, traditional throttle cables have largely been replaced by electronic control modules. These modules translate pedal pressure into electronic signals, allowing the vehicle's computer to precisely control acceleration. However, the Electronic Throttle Cable (ETC), also known as the "Drive by Wire" system, often suffers from delayed response and subdued acceleration, particularly during uphill starts, rapid gear changes, or when passing other vehicles.
Installing the Sprint Booster is a straightforward process – simply plug it in between your accelerator pedal module and the harness. The difference is instantly noticeable the moment you press the throttle. Should you ever wish to revert to your stock setup, removal is equally uncomplicated.
Rest easy with the protection of a money-back guarantee that allows you to experience the performance difference without any risk.

You may be able to upgrade the Shark Injector file to another version to better meet your tuning needs. Depending on the model we may have better tunes for things such as intakes, larger air sensors, camshafts, headers, and others. For a small fee the current Shark Injector tune can be removed and a new file added instead (the original Shark file you were using would no longer be available). To do this, we need the car restored to stock settings with the current Shark Injector and then returned to us (updating via USB is not yet available). Sharks that were not Restored to stock cannot be upgraded and the unit will be returned to you (at your expense). We also perform other work on the Shark Injector while it is here, including diagnostic tests and re-packaging with the most current instructions. The Shark that you get back is virtually new and ready to be reinstalled!
To get started, review the catalog of current Shark Injector files for one that better matches your tuning spec.
1. Enter the new tuning file in the form below. Include any other relevant information.
2. Click the Update Price or Add To Cart button.
3. Complete the online transaction with your address and payment information.
4. A Turner Motorsport sales rep will contact you after your order has been submitted. Do not send in your Shark Injector until someone has contacted you with a reference number and return shipping address.
Turn-around time for upgrades is typically the same day we receive it. UPS Ground is the normal return shipping method unless you specify faster shipping on your order.
