Frequently asked questions

How much bhp does Porsche Cayenne 958 4.2 TDI 385hp chip tuning add?

Power goes from 385 bhp to 450 bhp — a gain of +65 bhp (17%). Torque rises from 850 Nm to 950 Nm.

Will chip tuning damage the engine?

No. Values stay inside the safety margin the manufacturer leaves; engine, gearbox and turbo limits are not exceeded. Every file is verified with a road test and data logging. If the car needs maintenance first (worn injectors, blocked filter, weak clutch) we tell you before starting.

Will my fuel consumption go up?

With the same driving style it usually drops, because you hold the same speed at lower revs and less throttle. If you use the extra power, consumption naturally rises. It is down to your right foot.

How long does it take? Do I leave the car?

Most cars take 1–2 hours and you get the car back the same day; no need to leave it. Some models need the ECU removed, which takes longer — we tell you when booking.

Can I go back to stock later?

Yes. The original file is read and archived before any work. We restore the factory software free of charge whenever you ask.

Does it void my warranty?

Changing engine software can affect the manufacturer warranty. If a dealer finds a fault to be software related, they may refuse that claim. We want you to decide knowing this. Your original file stays with us and can be restored before a dealer visit.

Will it pass the roadworthiness test?

Stage 1 power software does not touch emission hardware. Work on emission systems is offered only for uses permitted by law; road use and inspection compliance remain the owner's responsibility.

How much does Porsche Cayenne 958 4.2 TDI 385hp chip tuning cost?

Price depends on the vehicle, the ECU and the solution chosen. Send us your vehicle details on WhatsApp and we will quote straight away. Inspection and measurement are free.

How is the work done?

We scan for faults and read the original software first. The file is adapted to your car's hardware, written, and verified on a road test. The original is archived.

Is DPF Delete possible on the Porsche Cayenne 958 4.2 TDI 385hp?

Yes. Our library contains a verified DPF Delete solution for the Porsche Cayenne 958 4.2 TDI 385hp. Once your original file is read, compatibility is checked and the job is applied.
