REVIEWS
Ben, Renault Master 2.5dci
My Renault master 2.5dci has improved by about 3 mpg, when doing 1000 miles a week its a great saving.
Andrew, Fiat Grande Punto 1.4i
I've only had my optimum for a week now but to be honest I can't feel any difference to performance or fuel economy. Maybe I have to drive more for it to adjust to my vehicle. I have been in touch with Tunit and they have A1 5 star customer service. They reply quick and respond very well to the emails. Overall seem like a decent company. Fiat grande punto 1.4 16v NA. Further to my last comments. I've drove about another 150 miles and I can notice an improvement midrange especially can feel more torque now. Good product.
