I've gone back over previous posts to see if anyone has already asked about these plug in electronic boxes which purport to increase BHP, torque and marginally reduce MPG but it seems not.
I've been checking out P-tronic (Belgium based company) as well as other suppliers e.g. Tuneit and reading the reviews, testimonials etc.
I live on Crete and because of the absurd Greek luxury car taxes it's prohibitive to buy large engine SUVs. It might come as a shock to learn that even my lowly 2.0D 2008 X3 cost 58,000 euros new and it has few if any of the goodies we all wish for. At present £1 is worth around 1.12 euros so you can work out just how expensive an X3 is over here!
Crete is also an island of hills and whilst the car performs well (it's the automatic version with the 177 BHP engine) it would be nice to have a little more grunt at the wheels. What's more, the cost of diesel here is now higher than the UK so better economy would not go amiss either.
Has anyone tried one of these gadgets on their X3 and if so I'd be grateful for some first hand reviews?
