Locked ECU? Already in the price. Every 718 with the 4.0 flat-six has a locked Bosch MG1 ECU. We unlock it on our own bench the same day, with no extra time, and the £449 is already included in the prices shown. You can choose to have it sent away instead: £399, 3–4 working days with the car staying with us. On its own, if we’re not tuning the car, it’s £549 in-house or £499 sent away. More on unlocking

Every price on this page is a full custom dyno tune

Not a generic file bought in and flashed over the port. Your Porsche Boxster is strapped to our in-house 4WD dyno and the map is written for your car, on the day, from its own data.

Health check firstWe look the car over and read the fault memory before we touch anything. If something is wrong, you get told. We don't map over a problem.
Live data loggingBoost, ignition timing, fuelling, knock and temperatures all watched in real time while the car is running under load.
Custom calibration on the dynoThe map is built and adjusted run by run against what your engine is actually doing, not what a file supplier assumed.
Before and after printoutYou leave with the graph: your standard figures and your tuned figures, measured on the same rollers, the same day.

Spread the cost. From £133.17/mo over 6 months at 0% APR with Bumper, interest free.

Porsche Boxster remapping questions

How much bhp does a Porsche Boxster gain from a remap?

It depends which engine you have. Across the 28 Porsche Boxster engines we tune, the 2.0T sees the biggest Stage 1 gain: 250bhp to 370bhp and 310Nm to 460Nm, up 120bhp. Every figure on this page is for that exact engine.

How much does it cost to remap a Porsche Boxster?

Stage 1 custom dyno tuning on a Porsche Boxster starts at £799 inc VAT. You can spread it over 6 months at 0% with Bumper, or choose Pay in full when you book and pay with Klarna.

What does Stage 2 need on a Porsche Boxster?

A decat or sports cat downpipe and an uprated intercooler. Stage 2 is not something we can map safely on a standard car, so without the hardware we would fit Stage 1 and you can step up once it is fitted.

Will remapping my Porsche Boxster affect my warranty or insurance?

A remap is an aftermarket modification, so it is your responsibility to declare it to your insurer. It may also affect any remaining manufacturer warranty. Our maps are fully reversible: the car can be put back to its factory software whenever you need.

How long does it take, and is it reversible?

Most Stage 1 tunes take around two hours, and if the ECU needs unlocking we do that on our own bench during the same visit, with no extra time. It is completely reversible: the car can go back to its factory software whenever you need.

Whichever you pick, the total carries through to checkout, so pay in full by card, Apple Pay or Klarna, or secure the slot with a £50 deposit. Figures are typical for a healthy, standard vehicle; your before and after dyno printout shows exactly what your car makes. Your car’s actual output depends on its condition, fuel quality and any supporting modifications. Prices shown are for Stage 1 custom dyno tuning inc VAT; locked ECUs (most BMW and Audi registered from mid-2020) carry an additional unlocking charge, confirmed when you book.
