Peter,Peugeot 407 2.2 HDI
I bought a Tunit unit for my 2.2l Peugeot 407SW and had it fitted and tweaked by Engine Tuners in Plymouth (and what a helpful, enthusiastic and friendly bunch they are!) Over my first 500 miles of motoring, 300 mixed and 200 towing a 1.5t caravan my computer tells me I'm getting 39.8mpg. Previous consumption without towing was 42mpg at best so I'm pretty pleased with the result. As for the improvement in power and torque, quite frankly I'm not so young as I was and I find it quite scary!
Runs a lot smoother more power well worth the money
