Diesel engine performance specialist tunit has got into the Christmas spirit and is offering a special gift giveaway to everyone who has a tunit conversion this December. Increased performance, and increased efficiency from tunit’s conversions are claimed to save up to 12% on fuel costs.

You get a three year warranty with all the work, which can either be dealer or self-fit, and the guys at tunit say that they have options suitable for over 2800 models. You also get a Christmas gift of a High Street voucher worth £50 if you have the work done on your diesel engine this December. That’s fuel saving and a great gift, so if you’ve been considering contacting tunit, there’s really no excuse for not picking up the phone, is there? Contact them on 0845 838 1405
