Diesel Engine Tuning: do or don't?
 

Hi,

Anyone experience with diesel tuning from 'serious' companies such as ACSchnitzer, Hamann, Hartge, ... ?

Does the extra horsepower affect the durability of the car?

In other words; engine tuning: hands on or hands off?

Please share your thoughts and experiences.

A chip upgrade would probably be the easiest way to achieve 20% more power and torque.

I think under the "International" selection, you can change countries.
Either way, you can take the chip out of the X5 and send it to Powerchip or perhaps a local chip upgrade company would be more convenient.
I have a 2005 Diesel 6 Speed manual. I have not done the upgrade, but a friend has done it on both his X5 and 530D and is extremely happy.

does the powerchip void your warranty? and does it actually work for non-turbo cars?

It vill void your warranty, and it wil give you some HP, but not as many as turbo engines get.

It is fine but your turbo is going to take the beating and the life of it wil shorten.
You dont have to go to Hamann or others, any plugin box will do the job.
If you plan on keeping the car for a long time you should consider replacing the turbo for a larger one an eaven intercooler

I have a power box in my Range Rover (same engine).

The difference is stunning. Whole other car!

RRD,
What's a power box?

A little box, plug and play.
It gives the engine 30-40 BHP more.

to RRD; How many kilometers has your car run with the box and how many more do you intend to do?

I got the box @ 165.000 km.

The car now has 180.000 km.

I intend to drive at least an other 100k km with this car. It's a brilliant car, and I don't buy a new car every 4 years.

Just drive her warm smoothly and don't hang in the kick down too much, and you this engine is almost unstoppable.
