REVIEWS

Mike,Isuzu Rodeo 3.0L

Very impressed. Noticeably improved acceleration and responsiveness as well as slightly better economy. Towing now much easier with heavy loads as well as being more fun to drive without. Well worth the money and much better value than paying manufacturer for same engine with higher power output.

Andy,Volvo s60

I like the economy the tunit offers but when the opportunity presents its self i love the increased power and acceration it generates. I tend to walk locally and only use my car (volvo s60)for journeys of any distance, however using your, Tunit, a k&n filter and shell "v" power diesel & keeping to 68/70 mph on a trip north up the a1 which included a long stretch of 50mph road works, at the end of which the cars on board computer was telling me i was averaging 75 miles to the gallon.... how good was that!!!! When trying something new the type of warranty your firm offers gave me the confidence to spend what first appears to be a lot of money.... something I wouldn't have done without the "try be for you buy" offer and the guarantee.
