Evo 7 — Stage 3 ECU Tune
- 122% power increase to 350kW
- Boost controller delivering 20psi by 4500rpm
- Enhanced intercooler efficiency for sustained performance
- Optimised cam timing for improved valve control
- Fuel system upgrade supporting E85 high-octane combustion
Factory 4G63 made 158 kW at the wheels. This is a full build intended for closed-circuit use, now sitting at 350 kW and 545 Nm on E85 through a larger turbo and supporting hardware. Haltech standalone gave us the headroom to map around 2.07 bar of boost safely.
The bigger turbo moves a lot more air than standard, so the intercooler and fuel system were brought up to match. Cams help the engine breathe at higher RPM, and solenoids give us proper boost control under load. The calibration prioritises consistent delivery across the throttle, keeping IATs in check and fuelling dialled for ethanol's cooling effect.
E85 gives us the knock resistance needed at this boost level, though you're chasing fuel stops more often. For competition or track work where the engine's going to see sustained load, the tune keeps timing conservative enough to hold together.
What sort of fuel consumption should I expect on E85 at this output?
E85 burns richer than pump fuel, so expect significantly shorter range, particularly under boost. On track or in anger, you'll be refilling often — plan accordingly for any extended use.
Is this setup reliable for regular competition use?
The hardware's all there and the tune's conservative on timing for the boost level, but any 350 kW build needs proper maintenance intervals and close monitoring of vitals. It's built for competition, not daily duties.
Can this calibration be adapted if I change the turbo or injectors later?
No. Any change to the turbo, injectors, or fuel system will need a fresh calibration. The map is specific to this exact hardware combination.
