Stage 2 Swift delivers 98 kW and 255 Nm with cooling and exhaust

The 2020 Swift responds well to a sensible Stage 2 approach. With a Greddy intercooler keeping charge temps in check and an Xforce downpipe freeing up exhaust flow, the ECU tune lifted power from 86 kW to 98 kW at the wheels, while torque jumped from 200 Nm to 255 Nm.

That's a 12 kW gain and a meaningful midrange bump that transforms daily driveability without asking too much of the factory platform. The intercooler upgrade is key here, especially during warmer months when heat soak would otherwise pull timing.

This is a practical street setup for front-wheel drive, keeping the factory turbo and fuelling while maximising what's there. Calibration focused on safe timing advance and boost control within the hardware's limits.

Common questions
Is the factory turbo retained on this Stage 2 file?

Yes. The tune works within the factory turbo's envelope, relying on improved cooling and reduced backpressure to support the power increase.

What's the torque gain like through the midrange?

Torque climbed from 200 Nm to 255 Nm, a solid lift that improves throttle response and in-gear acceleration without stressing the drivetrain.

Does this require upgraded fuelling or injectors?

Not recorded for this build. The gains suggest factory fuelling was adequate with the supporting hardware and calibration adjustments made.
