Mobile tuning in Bristol
ECU remapping in Bristol
Bristol is where most of our appointments happen. We bring ECU remapping, gearbox tuning and dealer-level diagnostics to your driveway or workplace across the city and South Gloucestershire, so the car never has to leave your sight.
Appointments that fit around city life
Most Bristol jobs are carried out on a home driveway or in a workplace car park, with the employer's permission. We need safe access around the vehicle and somewhere we can legally park alongside it, which matters in residents' parking zones and on narrow terraced streets.

If you live in a flat or on a busy road, a workplace or a friend's driveway usually works well. Tell us the postcode when you enquire and we will confirm what is practical before booking.

Bristol's Clean Air Zone and tuning
Bristol's Clean Air Zone charges older, non-compliant vehicles to drive in the central zone. Compliance depends on the vehicle's Euro emissions standard, which a remap does not change, so tuning will neither make a car compliant nor stop it being compliant.

If your DPF, EGR or AdBlue system is causing warning lights or limp mode, we can help diagnose and fix the issue on your driveway.

What Bristol drivers ask us for
BMWs are where we started and what we specialise in, and we tune Volkswagen Group, Mercedes-Benz and Ford vehicles too, plus vans used for work. Common requests are smoother, stronger mid-range response for motorway and ring-road driving, and gearbox tuning on automatics to sharpen shifts.

Every appointment starts with a diagnostic check and a free vehicle inspection. If something needs attention first, we tell you before any tuning is done.
How a mobile visit works
What to expect, from enquiry to handover.
Step 1
Send your enquiry
Your registration, mileage and what you would like to improve, through the quote form.
Step 2
We confirm and book
We check compatibility, give you a clear price and agree a date and place.
Step 3
We come to you
Usually your driveway or a private parking area, with safe access around the car and cover in poor weather.
Step 4
Checks, then tuning
Diagnostics and a free inspection first. If something needs attention, we discuss it before any tuning.
Step 5
Test and hand over
A final diagnostic check and a walk-through of the result. A straightforward Stage 1 visit takes around one to two hours.
