REVIEWS

Paul , Landrover Range Rover 3.6 V8

Both latest vehicles have benefited greatly in terms of performance and fuel saving and I have had several on the different cars i have owned. Would always recommend.

Mike, Fiat 500 1.3

First impressions with the 500 with the Tunit fitted are without doubt quite sensational. The engine is very free revving with a fantastic spread of torque right through to 4000rpm. When driven quickly you fly though the gearbox making the car a whole lot of fun. Its not just the top end of the rev range to benefit either, at 30mph put it in fifth and the 500 purrs along quite happily without any hesitation. Put your foot hard down from this speed and I would have expected an amount of judder and not much engine pick up, but no she pulls away a little slow at first but cleanly never the less. The engine is definitely more smoother and flexible you would definitely question the cars 1.3 litres if you didnt know for something of larger capacity. A little early to comment on fuel consumption yet but first impressions are for an improvement. My wife Lynne comments are that she has been razzing (women talk for driving briskly) with the car being so much more responsive and fun to drive, along with this has stated the on board computer showing an increase of some 2mpg even with the more enthusiastic driving. She has also said it feels a lot smoother. Generally very pleased the tunit it has had a big impact on the little 500. We will let you know a bit more after a bit more running.
