IF YOU EVER FOUND YOURSELF yearning for some extra poke with your smoke, or ideas on how to get your diesel engine running smoother than a baby’s rear, then Tunit could be the company to grant your wishes. 

They are a tuning company (obviously) that focuses entirely on diesel powered motors, which can only mean good things.

DPP cleans injection systems, provides a cetane boost and lasts for up to 12 months in the correct dosage, promoting a cleaner, more efficient diesel engine.
