Remote ECU tune · 7.3L Godzilla pushrod V8 (gas)
A custom Stage 1, 2 or 3 calibration for your Ford Super Duty 7.3 Godzilla V8, 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 Super Duty 7.3 Godzilla V8 makes 430 hp and 475 lb-ft (644 Nm). A Stage 1 tune typically adds 9–25 hp and 30–60 lb-ft, for around 439–455 hp in total. With bolt-ons and a Stage 2 calibration that grows to +25–45 hp, and a Stage 3 build — adding a supercharger or other forced induction, with the fuelling to support it — typically lands at 680–720 hp.

Tuner's notes
The naturally aspirated Godzilla gains mostly torque from a tune (+30 to +60 lb-ft peak on 87/93 octane) along with better 10R140 shift behaviour.
