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.

Just a quick feed-back for you following the fitment of your Tunit module fitted to my Mazda CX7 last Monday. On the drive from home to your establishment I averaged @42 mpg. Following the installation, on the drive from you to my mothers home I averaged 52 mpg! On the 200 mile drive from my mothers to my home I averaged 52 mpg! No flook then!! As indicated on the day, the car does run much smoother and the pickup and throttle response are much better. Great job guys, I shall be towing with the car soon so shall let you know how that goes also. Many thanks, Keith.
