I am in the process of making the egr plate, but I am concerned about installing it without having boost control as a mention of overboosting can be a result of blocking the egr off. Is it safe without this control?
Also reference is made to CRD's and having to allow partial flow. Which models are CRD? Mine is GU111 2002. (what is crd?)
What and where is the butterfly plate? And what are the benefits of modding this, and what is the actual mod?
Reading through all these posts is great fellas, it's like going back to school again.
Thinking about that, school was a bitch, this is much better.
