Hi,
I am thinking on doing some moderate tuning on my car, could anyone explain me what is done , modified in Stage one ? and what will be the result in therms of engine performance?
stage 1 has the same parameters no mater is made for a bmw or a renault ?

thank you

engine is an engine, understanding its working priniciple is basic, for more power you need more fuel , for more fuel you need more air...etc - brands are not important

Hi,
as seen in the attached picture, the modification % in a particular stage is true for a bmw 530d diesel engine and for a bmw 116i ?

in other words , stage 1 parameters rage are the same no matter for what engine do we want to use?

thanks

procentage tuning without any knowledge is why tuning is on bad name , your table is a great way to destroy an engine
