REVIEWS

Ken,Peugeot Boxer 2.8 HDi

I have just completed my first round trip and covered approximately 700mile with the Tunit VCR unit fitted on a standard setting, and I have to say WOW what a difference. The ‘pick up’ power from standing start is so much better. The cruising speed is definitely quieter and smoother, with less pressure on the accelerator, and the engine is more responsive for overtaking moves, and hill inclines. I haven't yet calculated the fuel saving, but hey, that will come later. I am very impressed and will keep you posted when I’m ready to update or upgrade. Next trip coming up is a Scotland run next week of around 1,200 miles. (can’t wait)

Steve,Jeep Grand Cherokee 2.8 C

Has made a significant improvement in both mpg and performance. Has smoothed out auto gear shift, reduced turbo lag and no more plumes of black smoke when accelerating hard. Overall really impressed, considering buying one for the Wrangler as well.
