Jonathon, Audi A5
Just wanted to add the NEW Optimum PLUS with Smart Phone control is an amazing bit of kit, less than 24 hours into using the upgrade but its brilliant, thanks again Michael and everyone at Tunit.
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.
