@TDIWyse

Looks like I could use the n55 mode of the p3 gage to get a reading...think it will work? Then again maybe not? bc the 0-5v of the MAP sensor may not be indicative of the the same boost pressure between the n55 and m57?

If you could have a look at: http://www.p3cars.com/bmw-install and scroll down to the "Config..." section of the page and read the notes next to "Cal.B" it would be a great help. I know I am asking a lot but I am noob at this stuff.

Can you definitively say that neither of the T fittings I took pics of will read boost?

@ anyone
There has got to be a boost indication somewhere besides the large intake pipe???
