Why your throttle feels sluggish - and how the SP18 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 SP18 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 SP18 does not add horsepower - it simply makes your existing power more immediately accessible.
