Whether you're after more performance, better economy, or need a fault properly diagnosed, every job starts with a full health check before any file is touched. Each service below has its own page with full detail, pricing and how it works. Some appointments may require a booking deposit, confirmed before you book.
Send the key vehicle details and I'll confirm compatibility, whether OBD, bench or boot access is required, the available options and a vehicle-specific quote before any payment.
This does not take payment or make a booking. Final suitability depends on the exact ECU, programming method, vehicle condition and diagnostic results.
A sample of the makes I work on regularly, if yours isn't listed, get in touch and I'll check compatibility.
Cars, motorcycles, vans and fleet vehicles all covered, ask about your specific make and model.
Not sure what any of this means? Here's the short version.
More power and a sharper throttle response, tailored to your vehicle and written specifically for your ECU.
ECU tuning aimed at smoother torque delivery and improved efficiency, particularly for cars and vans covering higher mileage.
Fault-code scanning and live-data checks to find the cause of warning lights and running issues before parts are replaced unnecessarily.
Diagnosis of recurring EGR warning lights and related fault codes, with clear advice on the right repair.
Fault finding for AdBlue and SCR system warnings, with guidance on the required repair.
On-car diagnostics, chemical cleaning and forced regeneration where suitable, with referral for replacement or specialist repair when required.
EGR, DPF and AdBlue/SCR software enquiries for verified competition, documented export or permanently non-road vehicles only. Options are shown on the relevant diagnostic pages.
All tuning is subject to a satisfactory diagnostic health check. Quoted power, torque or economy changes are estimates rather than guarantees and can vary with fuel quality, maintenance, modifications, mileage and mechanical condition.
Customers are responsible for notifying their insurer of any vehicle modification. A remap may affect manufacturer or third-party warranty cover.
Road-going vehicles: Myst Auto does not offer or quote DPF, GPF, catalytic-converter, EGR, AdBlue/SCR or other emissions-control deletion, bypass or deactivation for a vehicle that is, or may later be, used on a public road. I can offer diagnostics, DPF cleaning and regeneration where suitable, fault-code investigation and guidance towards a compliant repair.
Removing, disabling or obviously modifying manufacturer-fitted emissions equipment can make a vehicle unlawful to use on the road, result in an MOT major defect and affect insurance. Passing an emissions test does not by itself prove that a modified vehicle is lawful.
Competition, export and permanently non-road vehicles: Controlled-use EGR, DPF and AdBlue/SCR software enquiries are shown on the relevant service pages. I will not provide a quote, accept payment or agree work unless the vehicle's qualifying purpose, ownership, location and transport arrangements have first been reviewed in writing. A dedicated competition vehicle must be transported without using public roads; export enquiries require supporting evidence. SORN status or an “off-road use only” declaration does not by itself establish eligibility.
A customer's declaration is evidence only; it does not make an otherwise unlawful modification legal or transfer away Myst Auto's own responsibilities.
Customers must provide accurate information, be authorised to approve the work and notify their insurer or relevant authority where required. Myst Auto may refuse any work where the intended use or legal position is unclear.
Send me your registration and the fault you're seeing, and I'll advise on the best solution before you book anything.
