Graham ,Audi Q7 3.0 TDI V6

The Tunit fitted and working well. Additional power great but now getting 33 mpg versus the 25 mpg that I was getting. I originally left the setting at the default 5 and was getting about 29mpg, I thought by moving to 7, I would have increased power but reduced mpg, however the opposite has happened. I fitted the unit myself in the end, it was very simple to do.

Colin ,Toyota RAV-4

Very good customer care at gorse motors and very pleased with the performance of my Rav in all aspects ie better in the gears, able to keep in higher gear up hills,at present only had the unit ashort while but miles per gallon has improved cant wait to tow my caravan fill confident it will pull better.
