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. For Altrincham drivers, every job is handled personally by Samuel, no handoff to a junior technician, no generic file loaded from a remote server and pushed to your car.

Samuel works from data. The 4-Wheel-Drive Bapro dynamometer at the Eccles facility lets him monitor fuelling, boost pressure, ignition timing and knock events in real time across every run. He builds the calibration around what your specific engine is doing on the rollers, refines it, and confirms it against measured power figures before the car leaves the dyno. What you get at the end is a map built for your car, not a map built for a car like yours.

His reputation in performance tuning circles extends internationally, and the standard of work is the same regardless of which vehicle or platform sits on the dyno.

Why choose Manchester Dyno Centre

In-house 4WD dyno. The 4-Wheel-Drive Bapro dynamometer is at the Eccles facility and used on every job. No dyno time is shared with another facility, and all-wheel-drive platforms are handled correctly where most rolling roads cannot load them at all.

Professional-grade hardware. Kess3 and CMD tooling, not clone equipment. Both OBD and bench tuning (ECU removed) are covered, giving access to a wider range of platforms and ECU types.

The most decorated remapping business Manchester has to offer. Manchester Dyno Centre is operated by 117Speed, which has built its standing through consistent work rather than marketing.

No published prices. Every job is quoted for the specific vehicle and the work required. A flat rate would not reflect the difference between a simple Stage 1 on a diesel van and a Stage 2 build on a performance platform.

Services

Performance tuning, Stage 1 remap (software only), Stage 2 remap (mapped to your actual hardware), launch control coding and activation, flame, pops and bangs tune for enthusiast use.

Frequently asked questions

Who carries out the tuning at Manchester Dyno Centre?
Samuel Gunnell personally handles every job. There is no team of technicians, and no work is subcontracted or handled by a junior. Samuel reads the ECU, builds the calibration, runs the car on the dyno, and signs it off, from start to finish.
What vehicles and platforms does Samuel work on?

Cars and vans are both covered. Call to confirm your specific vehicle before booking.
Is it worth travelling from Altrincham for a remap?
Altrincham is approximately 20 to 25 minutes from the Eccles facility, a straightforward journey via the motorway network. The question worth considering is what you are getting for that journey: a calibration developed on a 4WD Bapro dyno by a tuner with over ten years of experience, with measured before-and-after figures documented before you leave. That is not the standard of service available from most remapping businesses within Altrincham itself.
What do I need to do to prepare my car before a visit?
Arrive with a full tank of the correct fuel for your vehicle. Ensure there are no outstanding fault codes, any stored faults should be investigated and resolved beforehand, as they can affect the tuning session. Declare any existing modifications when you call to book, so the right session and calibration approach can be planned.
