It's the silver device just below the air horn. The intake hose is connected to it. The plug is on the back. About 10 or 11 o'clock. End of rough running. I never heard of idling issues before. But I'm betting it's the programming on the RaceMe. If I recall, the stock tunes needed work.

We have some of the best custom programmers in the world here. Someone may be able to help you. Like @Double R Diesel I think he does RaceMe too. He's very busy so bear with him.
Do you mean the throttle valve? That is kompletly deleted. https://www.ebay.de/itm/New-6-7L-EGR...72.m2749.l2649
