The Ford Explorer ST is an already impressive SUV with its 3.0L twin-turbo EcoBoost engine and 10-speed automatic transmission, but it has tons of untapped potential due to factory limitations. Fortunately, several aftermarket tuners offer custom performance tunes that significantly increase horsepower, torque, throttle response, and overall drivability.

Whether you’re looking for a daily driver tune with smoother power delivery or an all-out performance tune to dominate the drag strip, this guide covers the best tuning options for the Explorer ST, including who offers them and what each tune provides.

Why Tune Your Explorer ST?

Before diving into the different tuning options, let’s explore why tuning is one of the best performance upgrades you can make for your Explorer ST.

✅ Huge Horsepower & Torque Gains – A tune alone can add 50-100+ horsepower and 100-150 lb-ft of torque on pump gas, with even more gains on E85 or race fuel.
✅ Eliminates Throttle Lag – The stock throttle response is sluggish; a tune makes it much more responsive and snappy.
✅ Optimized Boost & Fueling – Factory settings are conservative; a tune safely increases boost pressure and improves air/fuel ratios.
✅ Faster, Smoother Transmission Shifts – Many tuners refine the 10-speed auto’s shift logic, making it faster and more precise.
✅ Supports Bolt-On Upgrades – If you’ve added an intake, intercooler, exhaust, downpipes, or fueling upgrades, a tune ensures everything works in harmony.

Now, let’s explore the top tuning providers for the Explorer ST.
