REVIEWS

Rob ,Landrover Discovery TDI 2.5 Au

The landrover has inceased in both torque and power, but mostly noticeable in pulling the horse box up hills, rather than increased speed. But it is faster pulling away from junctions.

Paul ,Citroën C4

Had my tunit fitted same day I bought my new C4 especially noticed the increase in performance. Fuel economy can exceed 60mpg on a long run against mid 40s.
