Various engines have their own life expectancies depending on how they are driven and loaded. If you expect to have an engine life of 250k kms,, this will be shortened, depending on how the tuning box is adjusted to overdrive the engine, and how you drive your car.

Racing people know this, but they are after power and speed, not engine life.
Tama po ito im a deisel perfromance tuner po..................i install and tuned a fully programable chips in thailand, malaysia and philippines.

Pag gumamit po kayo nag Commonrail chip what it does is to increase the commonrail pressure above its limits, chips like this need to be balance with your commonrail. So if your chip is only a plug and play and no hardware alteration it only means one thing, nag sayang kayo nag pera, with out altering the commonrail you can not increase the pressure.

Other chip is use for the injectors, chips like this alter the timing. It will open and close depending on the programming and a bit higher on your FC.
Also will really shorten you injectors life. Think that diesel engine injectors and not cheap.

If you will not race your rig better stay stock, better for the fuel and the environment.
