REVIEWS

Tim , Mitsubishi Shogun Sport 2.5

Better performance, engine flexibility and response. Makes the shogun a _very_ good towing vehicle. Presently I have a camper conversion project in hand and will fit a tunit when complete.

Graham, Audi Q7

Had device retuned to fit my Q7, from Mercedes Sprinter. Found Tunit made throttle control smoother and better performance overall. MPG still needs working out, as I haven’t been on a long run.
