William,VW Marine SDI

Fitted it to the vw marine sdi 75-5 on the middle setting. Improvement right away, rpm increased from 3100 to 3550 with acceleration improved. Top speed also up on the Arvor 190 from a struggling 10 knots to a terrific 15.5 knots.

I am more than satisfied and no need to increase performance any more on the tunit. 100% thanks again.

Sefton,VW Crafter 2.0 TDi

I bought the Tunit Advantage 3 for my van and asked Michael to programme it for economy but even though it was set for economy the unit still has a dial of 9 yes 9 settings on it. My mileage is pretty consistent but I live in a hilly area and my van is pretty loaded so to get 26-30mpg or 320-400 miles per tank BUT if I go on a distance run down the motorway I’ll get close to 600 miles out of a tank!…it’s worth mentioning that I’ve got General Grabbers on the van as well
