Car remapping near Southport, Samuel Gunnell, Manchester Dyno Centre
Lead tuner Samuel Gunnell handles every job personally at the Eccles, Manchester facility, on an in-house 4WD Bapro dyno, with results confirmed before the car leaves.
The tuner
Samuel Gunnell has been remapping professionally for over ten years. He is the lead tuner at Manchester Dyno Centre, operating out of a 6,000 sq ft facility in Eccles, Manchester, and his work is in demand well beyond the North West. His reputation in the performance tuning world is international, the quality of his calibration files is recognised by a community that is not easily impressed.
For Southport drivers prepared to make the journey, every job is handled personally by Samuel, on an in-house 4-Wheel-Drive Bapro dynamometer. There is no handoff to a junior tuner, no file sent remotely without session confirmation, no generic calibration loaded and the car driven away. Samuel reads the ECU, builds or modifies the calibration, and runs the car on the rollers with fuelling, boost pressure, ignition timing and knock events visible in real time. The calibration is refined until the data confirms it is right. You leave with documented before-and-after power figures.
That level of personal involvement and equipment-backed confirmation is not common at any price point. The drive from Southport to Eccles is around 40 minutes, a straightforward run via the motorway network.
Why Manchester Dyno Centre
In-house 4WD dyno. The 4-Wheel-Drive Bapro dynamometer is owned and operated by Manchester Dyno Centre, not shared with another facility, not hired in for the day. Every map is verified on the rollers as a matter of course.
Professional-grade hardware. Kess3 and CMD tooling, OBD-port and bench read-write for a wide range of platforms. Not clone equipment. The hardware matters because bench access is required for certain ECUs that cannot be reliably read via OBD alone.
117Speed. Manchester Dyno Centre is the operating name for 117Speed, recognised as the most decorated remapping business in Manchester and the number-one tuning facility in the North West.
No published prices. Every job is quoted individually. No two vehicles require the same session, and the quote reflects the specific car, platform and work required.
