Topgear Tuning has launched an engine remapping service for fleet vehicles which it claims can deliver fuel savings of up to 15%.

'The Original Stig' and ex-racing driver Perry McCarthy, co-owner of the company, said: "Topgear Tuning is a leader within the ECU remapping industry and by careful reprogramming of your vehicle fleet our qualified technicians can deliver fuel savings of up to 15%.

"We estimate that, for example, a medium-sized logistics group which run 200 HGVs cover a combined 14 million road miles each year.

"Its current fuel cost is £8.75 million pounds per annum. After our negotiated contract costs are applied, we could jointly target fuel savings of up to £1.3 million per year. If a group normally operates their vehicles over a period of three years, this could equate to total savings of just under £4 million."

Topgear Tuning uses ‘economy’ remap files to reprogram fleet and commercial vehicles, including HGVs, trucks and vans.
