REVIEWS

R.,Alfa Romeo GT 1.9 JTD

The tunit box is fantastic, there now seems to be loads more power throughout the rev range and the noticeable turbo lag that was there before has all but gone. Also the average fuel consumption has improved by about 3-4 mpg! It's also good how easy the box is to remove if need be, 10 minute job. It really has increased my enjoyment of the car, I really can't fault it, worth every penny.

Fantastic company to deal with. Tunit gives the vehicle more drivability and low down torque great for either towing or carrying heavy cargo. Inturn you get better mpg due to staying in top gear over longer periods. Used them for years wouldn't go anywhere else.
