We're based in Bristol

BR Tuning & Diagnostics are Custom Remapping Specialists offering vehicle remapping on cars, vans and bikes.

At BR Tuning & Diagnostics the customer is our main priority, so to make your life easier we are mobile so can remap your vehicle anywhere within a 10-mile radius of Bristol with zero additional cost, we will also travel further for a small additional cost.

BR Tuning & Diagnostics have years of valuable experience and can remap almost all vehicles made since 2000. We believe drive-ability is as important as anything else so all of our maps are designed with that in mind. We often get asked about rolling roads, printouts etc and our answer is always the same, these are about vanity and have no reference to how the car actually drives. We are regularly attending vehicles that have been tuned by X company, they have produced great figures but the car has now got this issue or that issue, the tuner doesn’t want to know.

All of our maps are custom-made by specialist mapping file writers with a huge wealth of experience. This means the modifications made to your vehicle are done to the very highest standards using only genuine software, as well as straightforward mapping.
