REVIEWS

Ray,Jeep Cherokee 2.8

Throttle response below 2000rpm is much improved which means less gear changing and smoother progress in town traffic. Official MPG combined figure for my Jeep Cherokee is 33.9. At present with Tunit fitted, it is returning circa 38 MPG and I expect even better re¬sults as the mileage increases and the engine loosens up.

Tunit is the best.
