The ShiftPower SP27 is a plug-and-play throttle response controller that eliminates the acceleration lag built into your factory throttle system - giving you immediate, precise response every time you press the pedal. No tuning shop required. No permanent modifications. Just noticeably sharper throttle response from a single device that installs in minutes.

Professional local installation available in La Mirada, Southern California. Contact us at info@beatsonicusa.com to book.

Why your throttle feels sluggish - and how the SP27 fixes it

Modern vehicles use electronic throttle control systems with a built-in delay between pedal input and engine response. This lag is intentional from the factory - designed for emissions compliance and smooth driving - but it makes your car feel slower and less responsive than it actually is. The ShiftPower SP27 intercepts the signal between your accelerator pedal and ECU, recalibrating it to remove that artificial hesitation and deliver the full responsiveness your engine is capable of.

Your engine, emissions system, and vehicle warranty are unaffected. The SP27 does not add horsepower - it simply makes your existing power more immediately accessible.
