The Petrol Package provides the best in performance, savings and aftercare. Optimise your petrol engine with outstanding torque and BHP. Average fuel savings of 9%. Maximum control.
The Petrol Package allows adjustment through the Optimum Plus Phone App which actually increases or decreases BHP and torque. The dash control pad controls the delivery of that performance.
Every driver and every car is different. Although already pre-programmed and pre-set for your car, easy to use controls allow performance to be tailored to suit your driving style.
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.
