The manual in car adjusters are good but at the same time deadly in the wrong hands. Most people just install them in such a way that they can keep turning up the boost forever.

We all know in the heat of the moment you can get a bit power hungry, and if youve got the ability to run unlimited boost you sooner or later will take your luck too far and BANG!

If you buy one get it set up properly so you cant take it past a safe boost level.

And you would want to fit this before you have you rolling road set up done aswell!!
