Re: 4000 CS turbo Quattro
Just a few questions for you.
Do you have any overboost protection or computer controlled boost at all?
How is boost controlled? Is there any kind of protection against knocking
such as a knock sensor? Is there a way to back off the timing if things
such as the intake temps or water temps are high?
