Costly turbo diesel engines can be retuned to run more economically - by up to 20% in some cases - through the use of simple 'plug and play' technology.
Tuning firm Paramount Performance, which usually specialises in tuning performance cars for more power, has seen an increased demand for retuning turbo diesel engines so that they cost less to run.
The firm uses 'plug and play' economy devices or engine remapping techniques to improve the running of almost any kind of vehicle powered by a turbo diesel engine.
Paul Busby, Paramount's managing director, said: "In the current climate, reducing fuel consumption by even a few per cent can create huge annual savings across a fleet of trucks or vans. The relatively modest initial outlay of a few hundred pounds per conversion can be recouped in no time at all.
"In many cases we can dramatically reduce consumption while still providing an increase in power. Earlier this year we modified a Volvo F12 tractor unit, achieving an increase in power and better driveability on top of a reduction in consumption from 4.2mpg to 6.7mpg - an improvement of nearly 60%."
