What You Get For Your Money

Full health check first

We read your ECU and check the engine’s health before any tuning, we only ever tune a healthy car.

Before & after dyno printout

Every car is proven on our in-house 4WD dyno, so you leave with a printout of your real bhp and torque gains.

A bespoke custom map

Your map is written and tuned for your exact car and mods, never an off-the-shelf generic file.

Road test & final checks

We road test and data-log after tuning to make sure your car is safe, smooth and driving spot on.

Fully reversible

Your original file is saved, so we can set your car back to stock at any time you ask.

Pricing FAQs

Common Questions On Cost

How much does a Stage 1 remap cost?

Most BMW and VAG cars are £449 including VAT for a custom Stage 1 dyno tune. BMW B58 and M models, Audi RS and Porsche petrol range from £599 to £799, and prestige models are priced individually. Check the price table above for your exact car.

What is included in the price?

Every custom tune includes a full vehicle health check, a bespoke map written for your exact car, a before-and-after dyno printout, a road test and final checks. Your original file is saved so the tune is fully reversible, and all prices include VAT.

Are your prices inclusive of VAT?

Yes. Every price we show includes VAT. There are no hidden fees and no separate fitting charge added on top.

What is the difference between Stage 1 and Stage 2?

Stage 1 is a software-only tune that runs on your standard car with no extra parts needed. Stage 2 requires supporting hardware, such as a sports or decat downpipe, to be fitted first, and costs £150 more than the Stage 1 price.

Do I need gearbox tuning as well?

If your car is an automatic (BMW ZF/xHP or VAG DSG/S-tronic), a matched gearbox tune sharpens the shifts and helps handle the extra torque. Booked together with your engine tune you save £125 on the pair.

Do you offer finance?

Yes. You can spread the cost over interest-free 0% monthly payments, apply in a couple of minutes on our finance page.

How long does the tune take?

A Stage 1 custom dyno tune is typically around 2 hours. BMWs and Audis registered from mid-2020 have a locked ECU that needs in-house bench unlocking first. On a BMW that is quick on our bench, so the appointment stays its normal length; on an Audi it runs as a 4-hour half-day.

My car isn't listed, can you still price it?

Almost certainly. Use our Check My Car tool for an instant price, or send your details for a tailored quote. We also carry out DPF, EGR, AdBlue and ECU unlocking across most makes.
