Remapping the Peugeot 308 (2017), 1.5 Blue HDI 100HP.
A Stage 1 remap on the 1.5 Blue HDI 100HP fitted to the Peugeot 308 (2017) is firmly power-led: BHP climbs from 100bhp to 130bhp (a 30% gain), while torque rises a more modest 20% from 250Nm to 300Nm.
As a turbocharged diesel, this is exactly the kind of engine that responds well to remapping, and a transformative gain like this translates into stronger motorway pulling power and easier overtaking. These figures apply to 2017 models.
Typical remap gains for the 308 1.5 Blue HDI 100HP
Standard vs Remapped
Standard vs Remapped
- Power: 100bhp standard, 130bhp after a Stage 1 remap.
- Torque: 250Nm standard, 300Nm after a Stage 1 remap.
- This is a power-led gain: BHP increases by more than torque, widening the usable power band rather than boosting low-end pull.
- This is a turbocharged engine, which typically means further headroom exists beyond Stage 1 if hardware is upgraded.
- As a diesel, the practical benefit is mainly felt as stronger pulling power for towing and motorway overtaking.
- These figures apply specifically to 2017 models.
- These are Stage 1 figures only, achieved without any hardware changes.
Questions about remapping your 308 1.5 Blue HDI 100HP
How much power and torque does a Stage 1 remap add to the Peugeot 308 (2017) 1.5 Blue HDI 100HP?
A Stage 1 remap typically takes the Peugeot 308 (2017) 1.5 Blue HDI 100HP from 100bhp to around 130bhp, and torque from 250Nm to around 300Nm. This is a transformative gain achieved entirely through software, with no hardware changes required.
Is the Peugeot 308 (2017) 1.5 Blue HDI 100HP 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 Peugeot 308 (2017)?
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 Peugeot 308 (2017) 1.5 Blue HDI 100HP 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 Peugeot 308 (2017) 1.5 Blue HDI 100HP?
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 Peugeot 308 (2017). For a diesel like this one, also check the DPF and EGR are in good working order, since a generic remap on a struggling emissions system is where problems tend to start.
What's the difference between a Stage 1 and Stage 2 remap for the 1.5 Blue HDI 100HP?
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 Peugeot 308 (2017) 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 1.5 Blue HDI 100HP, expect a likely premium increase, and it is worth getting a quote from a specialist modified-vehicle insurer before booking the remap itself.
