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 Chorley drivers prepared to make the journey, every job is handled personally by Samuel, no handoff to a junior, no remote file delivery from someone who has not seen your car.

He works on the 4-Wheel-Drive Bapro dynamometer in-house, monitoring fuelling, boost pressure, ignition timing and knock events live throughout every run. The calibration is refined on the rollers until the data confirms it is right. Before you leave, you have documented before-and-after power figures, the measurement that proves the work, not a promise based on what similar cars typically make.

Samuel's reputation in the automotive tuning world extends internationally. Chorley is 22 miles from the Eccles facility. For work at this level, that is worth the drive.

Frequently asked questions

Who carries out the tuning at Manchester Dyno Centre?
Samuel Gunnell handles every job personally. There is no junior team member who steps in for less complex work. Samuel reads the ECU, builds or modifies the calibration, and runs every dyno session himself. That is consistent across every vehicle that comes through the facility.
What vehicles and platforms does Samuel work on?
BMW B58, N55, N57 and S55 engines. Audi and Volkswagen, Golf GTI, GTD and Golf R. Ford Fiesta ST, Focus ST, Transit and Ranger. Seat Cupra, Skoda Octavia vRS. Vauxhall Astra VXR and Vivaro. Mercedes. Petrol and diesel are both covered. Cars and vans. The 4WD Bapro handles all-wheel-drive platforms correctly.
Is it worth travelling from Chorley for a remap?
The 22-mile drive from Chorley to Eccles takes around 35 to 40 minutes. What justifies that journey is the quality gap between a generic file loaded from a laptop and a calibration developed and verified on your specific engine, on the dyno, by the same tuner who built the map. That gap is measurable, you leave with the before-and-after figures to prove it.
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, if there are, let the team know when booking, as some will need to be resolved before tuning can begin. Declare any modifications at the time of booking so the correct session length can be allocated.
