Mustang GT — Stage 1 ECU Tune
- 13kW power increase
- 9Nm torque increase
- Enhanced air intake efficiency
- Optimized exhaust flow
- Refined fuel delivery mapping
- Crisp clean power delivery
The 5.0L Coyote responds well to basic breathing mods and a recalibrated tune. This Mustang GT came in with a cold air intake and long tube headers already fitted — the sort of foundation that lets you tidy up fuelling, timing, and throttle maps without chasing peak numbers.
The workshop recorded 262 kW at the wheels before the tune and 275 kW after, with torque lifting from 425 Nm to 430 Nm. It's a 13 kW gain, not headline-grabbing, but the driveability improvement is where you feel it — cleaner part-throttle response and better calibration for the headers.
Stage 1 keeps the factory hardware intact. No cam swaps, no porting, just sorting what's there. On 98 RON and a hot day, the Coyote holds timing better with a proper base map.
Is 13 kW typical for a Stage 1 Coyote with headers and intake?
Yes, it sits in the expected range. The Coyote's factory tune is conservative, so headers and intake with a proper recalibration usually yield 10–15 kW depending on the baseline and conditions.
Does this tune require premium fuel?
Fuel type wasn't recorded for this file, but Stage 1 Coyote tunes are typically calibrated for 98 RON. Confirm with your Protunes rep before loading.
Will this work on a manual or auto GT?
This is an ECU-only tune, so it suits both transmissions. If you're tuning an auto, you may want a matched TCU file for shift firmness and timing.
