REVIEWS

Mike,Nissan X-Trail

I have put a link to Tunit on my website. Astounded at the improvement to my X Trail.

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.
