Note: This install is NOT that difficult. A less than experienced back yard mechanic can do this. The first attempt is very time consuming, because quite frankly, YOU are AFRAID to F*ck up YOUR S4! (took me 4 hrs). An expereinced back yard mechanic can do it in 1.5 hrs, or less (in my opinion).

There is one thing NOT shown here (no pics) - the electrical (power) connection to post 75x (STFA) and where I installed the ground wire (on the chasis - near the fuse box).

Also, you should look at the diagrams (on AudiWorld) that illustrate the connections for running a MBC and N75 in parallel. It will show you how the turbo and wastegate are plumbed into the N75 - u have to use the SAME connections on the Profec B - but YOU WILL NOT be running the Profec B in parallel with the N75.

Here Are The Pics (I hope that the text is helpful):


Profec B Stepper Motor (Turbo - Wastegate Interface) in coolest area of engine compartment

N75 is STILL Intact Electronically (so the ECU doesn't throw CELs)But the Wastegate and Turbo Connections Have Been Severed. N75 No Longer Controls Boost On My Car. Note the RED CAP on the N75 where the Wastegate hose was disconnected. There is a BLACK CAP where the Turbo hose was connected.

And EBC's were a no good piece of ricer ****. Now I've seen a couple of good EBC applications and it seems to be working well.

Kudo's for bucking conventional PEB wisdom and going out on a limb.

Or maybe it was just the Kamei Eyelids ;-)
