FAQs

Choosing The Right Service

The questions we get asked most when customers are deciding what to book.

Which should I get, Stage 1 or Stage 2?

Stage 1 is a software-only custom remap that needs no hardware changes, the right choice for most road cars, with strong, safe gains. Stage 2 builds on supporting hardware such as a sports cat, downpipe or upgraded induction. Not sure which fits your car? Send us your details and we'll advise honestly.

Can you tune the engine and gearbox together?

Yes. On ZF8 (BMW) and DSG / S tronic (VAG) cars we tune the engine and gearbox together so they work as one. The gearbox calibration, xHP or TCU, sharpens shift speed and raises torque limits to match the engine tune, and we'll usually do both in the same visit.

Do you offer DPF, EGR and AdBlue solutions?

Yes. Diesel emissions systems cause a large share of running issues, so we always diagnose the root cause of DPF, EGR and AdBlue / SCR faults first, then advise the right solution to restore healthy, reliable running. We'll talk you through the options for your specific vehicle before doing anything.

Will a remap improve my fuel economy?

We tune for performance, not fuel economy, so we don’t promise or guarantee any MPG saving. How much fuel the car uses comes down mostly to how it’s driven, and using the extra performance will use more.

Do you tune my make and model?

We're BMW and VAG (Audi, VW, SEAT, Škoda, Cupra) specialists and tune these platforms every day, from 20d and 30d diesels to M340i, Golf R, Audi S3 and beyond. We tune other makes too; send us your reg and we'll confirm exactly what's possible for your car.

How do I get a price?

Send us your registration, or your make, model and year, and we'll come back with pricing and the expected power and torque gains for your car, no obligation. It takes a couple of minutes on our quote page.
