Cool- I really cannot wait until I get it back from the dealer. Hopefully they didn't tap into any wires etc and followed the video / PDF. Btw Rick, I mentioned this to Tim as well- the video is for N54, so we had a tough time with my 2011 N55 as a result in some places- is there a video you kind fellas have for specifically the N55- some things are significantly different, especially during the vacuum boost section and running the tubing etc.

It also can read boost over canbus for flash tunes or stock cars, or from it's own analog sensors with a vacuum line. 3 ways to go about it.

Hi, well..im writting you because im thinking of buying the P3 gauge and I have some doubt.

Well, my problem is that I have installed the JB4 in my car and I want to install the P3 but after reading some forums, now I know that I have to use analog blue wire tap on map sensor like you said. My question is . how can I do that. Do I have to connect this blue wire directly to the brown wire that come out from the map sensor of the manifold? Could you send me a picture of the connection please? Im new in this.

Let me know please.

Thanks and sorry for my english.... Im from Chile
