I had to write you a note to say how most impressed I am with the box I had off you for my saab 95 TDI. It runs faster, smoother and better on diesel. I am a very happy man and thank you for the help you gave me.

Having your own horsebox is great, especially if it has full living and you can organise weekends away. It provides a much better ride for the horses especially on longer journeys. Taking friends and their horses along adds to the enjoyment and makes owning a horsebox a wonderful social event. The downside is the cost of keeping it maintained and on the road, even with newer models. To get the best from them you need to use them regularly. I was persuaded to take my horsebox to Tunit to try to achieve better fuel consumption and improve the emissions. If I am honest I didn’t really expect it to drive any differently, I just wanted to be a more responsible truck owner. Prior to the fitting, the technicians at Tunit had researched my engine and assessed which unit was the most appropriate to fit; this was rechecked when I arrived and the engine was viewed. The technicians I met were all very enthusiastic and knowledgeable about their product; they explained the process and fitting as they went along and were able to answer all the questions I had. They took enough time and care to do the job to a high standard, the only negative for me was that the job took a little longer than anticipated, as some of the tools weren’t big enough for this type of vehicle! When driving a horsebox it feels very different when it's heavily loaded compared to when it's empty however, even on the journey home I could already feel a difference in performance. I was familiar enough with how the vehicle normally handles on these local roads to notice a definite improvement in low-end power. The power is spread over the whole range of the gear which means you can accelerate evenly without hitting the rev limiter even on inclines and hills. You don't seem to need to work the gears constantly just to keep the truck moving evenly – this is especially important when you are fully loaded and I can see that this will help improve the quality of the journey for the horses. It is still a little early
