Remote ECU tune · 3.5L EcoBoost twin-turbo V6
A custom Stage 1, 2 or 3 calibration for your Ford Expedition / Navigator 3.5 EcoBoost, built by hand by a real tuner from your own stock file and datalog, and back with you within three hours of the file arriving. We tune these cars remotely, worldwide: you read and flash with your own HP Tuners interface, and you pay only once the tune is delivered.
Stock vs tuned
From the factory the Ford Expedition / Navigator 3.5 EcoBoost makes 375 hp and 470 lb-ft (637 Nm). A Stage 1 tune typically adds 40–100 hp and 45–120 lb-ft, for around 415–475 hp in total. With bolt-ons and a Stage 2 calibration that grows to +80–120 hp, and a Stage 3 build — a hybrid or upgraded turbocharger, with the fuelling to support it — typically lands at 525–625 hp.
