2nd Tunit I've had. the first one has been on two Saab 93's, a Volvo V60 and now a Merc C350 - very impressed with economy improvement, drivability and increased performance - a good investment. If everyone knew what it could do you'd be unable to keep up with demand. Who wouldn't buy a product that effectively ups your engine performance to the next cubic capacity up in the range, yet drops the fuel consumption to the next model down - so it pays for itself and the kick in the backside is a bonus - it's a no brainer.

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.
