Performance tuning files
Stronger power delivery, sharper throttle response and in-gear acceleration you can feel. Calibrated for the specific engine and its condition — never a one-size-fits-all file.
Tuning file service
Tuning file service — with a local workshop in Peterborough
At TuningFiles AT we deliver a tuning file service first: performance and economy calibrations plus DPF, EGR and AdBlue file solutions, built per vehicle and archived. And if you're in Peterborough or within sensible driving distance, we also do the work on your car locally — local service prices agreed individually over WhatsApp.
Services
Tuning files are the job. The workshop is where we prove them.
Remapping is a crowded trade, and most of it is invisible to the customer — you cannot see the file that goes into your ECU. TuningFiles AT is built around a tuning file service you can interrogate. Ask what the calibration changes, ask what was checked before it was written, ask for the measured output. You will get straight answers.
Performance tuning, economy tuning, custom dyno calibration and DPF, EGR and AdBlue solutions are quoted as separate routes because they are different jobs. A Stage 1 file for a healthy standard engine is not the same piece of work as a diagnostics-led file for a vehicle with faults.
On top of the file service, we offer local ECU remapping in and around Peterborough — you bring the car, we handle the whole job end to end. Local service is priced individually: message us on WhatsApp with the vehicle details and you'll get a straight number for your car.
What we do
Our most popular services
Economy tuning files
For drivers and fleets that want smoother torque and sensible fuel use. Focused on drivability and efficiency, and honest about what a calibration can and cannot save.
Custom dyno tuning
The vehicle is tested under controlled load so the calibration can be proven against measured output. The route for modified cars and anything beyond a standard stage file.
DPF, EGR & AdBlue solutions
Diesel-system faults cause limp mode, warning lights and expensive guesswork. Diagnostics come first — a file decision is only made once the hardware story is known.
Local service in Peterborough
All of the above done on your car at the workshop — Stage 1, Stage 2, DPF, EGR, flaps, AdBlue and more, for Peterborough and a sensible radius around it. Local service prices are set individually for each vehicle — quickest way is WhatsApp: send make, model, engine and what you want.
Vehicles we calibrate
From German saloons to working trucks and field machinery
One disciplined file workflow covers all of it: read the original, build the calibration, prove it, archive everything. Ask for your exact engine — the quote comes from real calibration data.

FAQ
Straight answers to the usual questions
Do you only tune vehicles in Peterborough?
No. Local ECU remapping is available for Peterborough-area customers, while the tuning file service can support trade work from an original ECU read. The quote route depends on whether you want the full job done on the vehicle or a prepared file returned to you.
Why do you ask for vehicle details before giving a price?
Because the same model name can hide different engines, ECUs and fault histories. Make, model, year, engine, gearbox, current faults and the result you want are enough to price the real job instead of guessing from a generic menu.
What happens to the original ECU file?
The original file is saved before a modified file is written. That gives the vehicle a documented route back to standard and keeps the calibration history clear.
Do you work with DPF, EGR and AdBlue problems?
Yes, but diagnostics come first. Warning lights, limp mode and regeneration issues can be caused by hardware, sensors or software history, so the fault picture is checked before a file decision is made.
Can you tune vans, trucks and agricultural machinery?
Yes. The site covers cars, vans, HGVs and agricultural machinery because the same file workflow can be applied to different working vehicles. The goal changes by vehicle: response, torque, economy, reliability or measured custom output.
What is the quickest way to get a quote?
Use WhatsApp, phone or email with the vehicle details and what you want done. If it is a local Peterborough job, say that. If it is a trade file request, include the original read and any software ID you have.
