VF SS VF — Stage 2 ECU Tune
- 307kW at the wheels
- 509Nm torque delivery
- Strong power across rev range
- Sharper throttle response
- Enhanced V8 engine character
This VF is running a proper naturally aspirated recipe: VCM 122 camshaft, Blackwell ported heads, upgraded valve train hardware and a mafless tune to tie it together. The result is 307 kilowatts and 509 newton-metres at the wheels, which is solid output for a Stage 2 V8 on pump fuel.
The mafless approach gives better control once you've shifted the volumetric efficiency this far from factory. The heads and cam lift the breathing ceiling, and the tune pulls it all into line without the MAF becoming a restriction or throwing curve balls under load.
Good street manners with the extra mid-range you'd expect from this combination. The workshop supplied the dyno figures after finalising the calibration.
Why run mafless on this build?
With ported heads and an aggressive cam, airflow characteristics change enough that removing the MAF and tuning with speed-density gives cleaner fuel control and removes a potential restriction.
Is 307 kW realistic for a Stage 2 naturally aspirated VF?
Yes. With a VCM 122 cam, ported heads and upgraded valve train, 307 kW at the wheels is consistent with what you'd expect from a well-sorted NA combination on 98 RON.
What supporting hardware is needed for this spec?
Upgraded lifters and buckets are listed to handle the VCM 122 cam profile. Beyond that, expect the usual: valve springs, pushrods, and appropriate tuning to match the new airflow.
