Title: 01 S4 Table differences between stock Hitachi MAF and Bosch RS4 MAF Post by: wickster on October 27, 2010, 08:11:18 AM Car: 2001 Audi B5 S4
ECU: 8D0997551M 0002 Engine mods: K04 turbos, 85mm MAF housing with Hitachi MAF, Siemens 630cc/min, (60lb/min) injectors, Green coolant temp sensor Currently wanting to try to start from scratch so this will be my log of the changes I've made based on research and the help of this forum.

I was reaching the limit of the stock MAF housing at 5800 RPM with my K04s, I'm now within the range of the 85mm scaling at all times.
