On return after fitting at Killinghall Quarry Industrial Estate, my Rover 75 Diesel ran smoother and had a hell of a lot more "Get up and Go" I bought the car two weeks ago checked all of the Mots that had been done at the DVLA to establish it's 32,260 miles showing on the oddometer. David who fitted the unit at Killinghall was a joy to behold, nothing too much trouble He even fitted me a Top grade Air filter which I took there with me and he would not charge, a first class young man in my estimation a totally joyous experience. Am I glad I found www.tunit.com I sure am.
