What a cracking piece of kit … Loving the sport mode

Noticeable difference, long term will definitely be worth the money

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.
