fwiw, s-cars with a single, metal debris screen on the maf don't see as much gain from its removal as a maf sensor with a metal debris screen+plastic flow straightener. On my 2001 MAF for the S4, I only saw 2-3 g/s gain across the board. Besides, I like the extra security of that debris screen just ...

fwiw, that ecs valve doesn't work on the S4 here in the states. the boost spikes to above 1.5 bar, then the ecu shuts the car down a bit by pulling the throttle shut. I guess some TT guys had good luck with it. You might want to just consider leaving the N75 plugged in and run a manual boost control...

super sweet. thanks Bushy. Do you want to see an S4? I can dig one up tomorrow or so. I should take a picture of our populated pins for you. [img]images/graemlins/notworthy.gif[/img]

rip that little flapper out of the front of the airbox where your lower velocity stack resides. if you can route a hose to that, it would be great. otherwise, i rotated that velocity stack 180 degrees...you'll see why when you look at it. I'm sure it don't make a huge difference though. heck, if you...

Hi there everyone...I have a question regarding the RS4 MAF sensor (Bosch). It seems that many of the Bosch MAF's are being upgraded with sensors that have a diode (possibly zener) across the empty terminals of the old sensors. The S4 sensor does not use the diode that you have on your sensors. Even...
