Back in the of my old TDi Leon I had a friend who owned a golf TDi with same engine (1.9 TDi 110 bhp) he had this thing that plugged into the engine where you could change the cars BHP/Torque levels. Any how after time he sold his car and fitted this new box thingy to my car.. any way it was great ok so a tiny bit Smokey but great fun, made loads of diff to my car, I could change the car for how I wanted it depending on where and how I was driving.. Now I’ve sold the car, but before it left me I took out this box thinking maybe its going to be worth something to someone one day…. But now I’ve no idea what to call it? Is it a chip/power box? Does anyone wanna make me a offer? lol
