The tuner

Samuel Gunnell has been remapping professionally for over ten years. He is the lead tuner at Manchester Dyno Centre, based out of a 6,000 sq ft workshop in Eccles, Manchester, and his reputation for tuning file quality extends well beyond the North West. His work is recognised internationally in the performance tuning community, he is not a local operator building a local profile. He is a specialist at the top of his trade, operating from a facility that is worth the journey.

For drivers making the trip from Leek, that distinction matters. Every job at Manchester Dyno Centre is handled personally by Samuel. There is no junior doing the baseline runs, no generic file loaded while he watches from the office. He reads the ECU, develops the calibration, monitors fuelling, boost pressure, ignition timing and knock events in real time on the 4-Wheel-Drive Bapro dynamometer, and refines the map on the rollers until the data confirms it is right. You leave with documented power figures, before and after, measured on the same day.

That level of personal involvement is not common in this trade.

Why Manchester Dyno Centre

In-house 4WD dyno. The Bapro dynamometer at the Eccles facility is owned and operated by Manchester Dyno Centre. It is the working tool for every job, not shared, not rented, not sourced from another facility for specific sessions.

Professional-grade hardware. Kess3 and CMD tooling covers both OBD port access and bench work for a wide range of ECU and TCU platforms. Not clone devices, not compromised hardware.

The 117Speed name. Manchester Dyno Centre is powered by 117Speed, the most decorated remapping business in Manchester. The track record behind that name is what draws drivers from across the Midlands and the North West.

FAQs

Who carries out the tuning at Manchester Dyno Centre?
Samuel Gunnell, personally. He is the lead tuner and he handles every job from start to finish, baseline runs, ECU read, calibration development, dyno refinement, and final confirmation. There is no delegation at any stage of the process.
What vehicles and platforms does Samuel work on?
Samuel works on BMW (B58, N55, N57, S55), Volkswagen Golf GTI, GTD and R, Audi with Quattro, Ford Fiesta ST, Focus ST, Transit and Ranger, Seat Cupra, Skoda Octavia vRS, Vauxhall Astra VXR, and Mercedes. Both petrol and diesel engines are covered, including vans and commercial vehicles.
Is it worth travelling from Leek for a remap?
If you want a dyno-confirmed map built for your specific engine rather than a generic file, yes. The drive from Leek to Eccles is around 45 to 50 minutes, a reasonable journey for work that produces a documented, before-and-after result on a 4WD dyno rather than a calibration loaded from a car park. Drivers from further away make the trip regularly.
What do I need to do to prepare my car before a visit?
Arrive with a full tank of the correct fuel for your engine. Make sure there are no outstanding fault codes, have them investigated before your appointment. Declare any modifications when you book, as this determines which service is right for your car and how long to allow for the session.
