Remapping the Peugeot 807, 2.2 HDiF 170HP.
On the Peugeot 807, the 2.2 HDiF 170HP responds to remapping mainly through extra BHP, broadening the usable rev range, with power up 14.7% to 195bhp and torque following at a gentler 10.8% to 410Nm.
Turbocharged diesels are the classic remap candidate, and this worthwhile improvement is felt mainly as a stronger mid-range, with less need to work the engine hard to access the extra performance.
Typical remap gains for the 807 2.2 HDiF 170HP
Standard vs Remapped
Standard vs Remapped
- Power: 170bhp standard, 195bhp after a Stage 1 remap.
- Torque: 370Nm standard, 410Nm 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 are Stage 1 figures only, achieved without any hardware changes.
Questions about remapping your 807 2.2 HDiF 170HP
How much power and torque does a Stage 1 remap add to the Peugeot 807 2.2 HDiF 170HP?
A Stage 1 remap typically takes the Peugeot 807 2.2 HDiF 170HP from 170bhp to around 195bhp, and torque from 370Nm to around 410Nm. This is a worthwhile gain achieved entirely through software, with no hardware changes required.
Is the Peugeot 807 2.2 HDiF 170HP a good candidate for remapping?
Generally, yes: as a turbocharged engine it has the headroom to respond well to a quality remap, and the worthwhile 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 807?
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 807 2.2 HDiF 170HP 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 807 2.2 HDiF 170HP?
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 807. 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 2.2 HDiF 170HP?
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 807 affect my insurance?
Yes, always, a remap is a modification and must be declared to your insurer regardless of size. Given this worthwhile gain on the 2.2 HDiF 170HP, expect a likely premium increase, and it is worth getting a quote from a specialist modified-vehicle insurer before booking the remap itself.
