how to tune my diesel engine

Hello to all.

I am newbie in this area so I have a lot to learn. My aim will be to understand how to tune my engine. I have a Peugeot 407 2010, 3.0 HDI V2 biturbo. Except for how to make this (increase the fuel, and the modification of the other parameters) I need to know what software I will need to do that and of course what hardware.

I have to say I live in Europe.

It is easier to ask directly some people to already know that instead of make same research because i don t know what to search.

Of course after i will learn and i will be able to do myself this kind of simple tuning (stage 1) i want to be specialist for diesel engines made by Peugeot.

Many thanks for understanding and for help.
