REVIEWS

colin, Toyota Rav 4 2.0 D-4D

Have been running Rav on setting number 8 for a while and fuel consumption on average about 5% better than standard but because the engine responds better I do tend to drive quicker than I should so don't save as much as I probably could. Torque much better because I can drive in higher gears at lower speeds than standard set up. Tows 2008 Swift Challenger 480 really easily without too much gear changing. Have recently moved the control to number 9 and so far seems to have improved performance and torque even more. I was talking to fellow tower with standard Rav 2.0 D4D and he was saying he was disappointed that he had to keep changing gear when towing due to lack of torque. I did give him your phone number. Very pleased with the system in general. Easy to fit except for the silly place Toyota put the fuel rail connector plug.

Ian, Skoda Octavia 2.0 TDI

Hi, Congratulations and well done for the help you have given our troops in the battlefield. I am sure the whole country would echo our thanks if they were aware of how Tunit have been able to resolve the problems they had been experiencing.

My son has proved over and over just how good Tunit is at boosting performance in his fast response Skoda Octavia and it is just possible that by cutting his running time to serious incidents Tunit may have indirectly contributed to saving lives. At the very least this has helped the victims get the earliest possible attention from a highly trained doctor and this alone must have been of great relief and comfort not only to the victims but to all those involved on scene.

He also has the added bonus of economy and reduced emissions so it is a total Win! Win! Situation to use Tunit.

I am so pleased that I recommended Tunit to him.
