Stage 1 Remaps
More BHP, more torque, better MPG.
Our Stage 1 ECU remaps unlock the power your manufacturer left on the table. Custom-written files deliver smoother throttle response, stronger mid-range pull and improved fuel economy on motorway cruising — all within safe factory tolerances. Suitable for most petrol and diesel cars, vans and 4x4s.
Learn moreEGR Solutions
Software fix for sticking or blocked EGR valves.
EGR valves clog with carbon and cause limp mode, rough idle, smoke and warning lights. Our EGR software solutions resolve the underlying ECU behaviour cleanly and reliably — ideal for high-mileage diesels suffering repeated EGR failures.
Learn moreDPF Solutions
For failing or constantly blocking DPFs.
If your Diesel Particulate Filter is failing, blocking repeatedly or triggering forced regenerations, our DPF software solutions correct the issue at ECU level. We always advise on the legal and MOT implications first and recommend mechanical repair where appropriate.
Learn moreAdBlue Solutions
Reliable fix for faulty AdBlue / SCR systems.
AdBlue and SCR systems are notorious for sensor faults, pump failures and countdown warnings. Our AdBlue software solutions resolve persistent faults on Euro 5 and Euro 6 diesels — no more dashboard countdowns or non-start warnings.
Learn moreSpeed Limiter Removal
For vans, commercials and applicable cars.
We remove or raise factory speed limiters on vans, commercial vehicles and supported passenger cars. Fully reversible at any time. Particularly useful for fleet operators and tradespeople running motorway miles in vehicles capped well below capability.

“Amazing service! Mapped my Polo TSI to Stage 1 within 24 hours notice. Rescheduled with me to suit me better and done it outside my house. Would definitely recommend to anyone — really nice guy and works around you. Will definitely be after something again in the future!”

“Absolutely outstanding service from Paul. We were completely stranded at the roadside in Cardiff city centre on a miserable January evening and contacted him at very short notice. Paul came out promptly, was incredibly professional and knowledgeable, and didn't rush the job at all — he stayed with us until around 8pm to make sure everything was sorted properly. Kind, calm, and genuinely helpful throughout what was a very stressful situation. A true professional and a credit to his trade.”

“Thanks Paul for my Stage 1 remap today on my M140i. Was a bit unsure on having it first but felt reassured after meeting you and seeing other people's reviews beforehand. Lovely guy — absolutely changed the performance of my car, even more of a beast now. Will be using you again in the future on my next car.”
