Questions about remapping your i20 1.0 T-GDi – 120HP

How much power and torque does a Stage 1 remap add to the Hyundai i20 (2014-2018) 1.0 T-GDi – 120HP?

A Stage 1 remap typically takes the Hyundai i20 (2014-2018) 1.0 T-GDi – 120HP from 120bhp to around 140bhp, and torque from 172Nm to around 230Nm. This is a transformative gain achieved entirely through software, with no hardware changes required.

Is the Hyundai i20 (2014-2018) 1.0 T-GDi – 120HP a good candidate for remapping?

Generally, yes: as a turbocharged engine it has the headroom to respond well to a quality remap, and the transformative gain shown here reflects that. The main caveats are condition, not the engine itself, a healthy service history, no outstanding fault codes, and (for diesels) a clear DPF and EGR are what actually determine whether this particular car is ready for a remap.

Will remapping affect the warranty on my Hyundai i20 (2014-2018)?

A manufacturer can only void the parts of a warranty that the remap directly affects, not the entire vehicle, under the Consumer Rights Act and EU Block Exemption principles. In practice, on a Hyundai i20 (2014-2018) 1.0 T-GDi – 120HP this usually means engine and transmission-related claims are the ones worth discussing with a reputable tuner before booking.

What should I check before booking a remap for my Hyundai i20 (2014-2018) 1.0 T-GDi – 120HP?

Before booking, confirm the tuner uses a custom or bespoke file rather than a generic off-the-shelf map, ask whether they do a pre-remap health check, and check service history and mileage on your specific Hyundai i20 (2014-2018).

What's the difference between a Stage 1 and Stage 2 remap for the 1.0 T-GDi – 120HP?

Stage 1 is software-only and is what the figures on this page reflect. Stage 2 builds on that, but on a turbocharged engine like this, Stage 2 usually adds further gains but requires supporting hardware such as an upgraded intake or exhaust, so it is a separate conversation with a tuner rather than an automatic next step.

Will remapping my Hyundai i20 (2014-2018) affect my insurance?

Yes, always, a remap is a modification and must be declared to your insurer regardless of size. Given this transformative gain on the 1.0 T-GDi – 120HP, expect a likely premium increase, and it is worth getting a quote from a specialist modified-vehicle insurer before booking the remap itself.
