Often when I speak of favoring low end performance from my S4 this viewpoint is met with questions about why I wouldn’t just downshift to keep the car in a powerband.
To determine where I operate the car most often during typical driving I logged rpm during a typical drive and created the histogram below to show at what RPM I most often find myself, and why I’d select a turbo that has a strength in this region.

Since I spend the majority of time at a lower rpm I prefer to have a setup that will respond favorably while in this region.
In addition to receiving the Eurodyne Boost Manager back, described below, I received a K-type thermocouple from Auber instruments that I intend to use in conjunction with the Innovate LMA-3 Aux Box to take some high temperature readings.

I’ve been encountering difficulty with getting the Eurodyne Boost Manager water injection controller to work. After contacting Eurodyne they informed me that there have been some updates to the component and advised me to send the controller back so they could send me the current version.
I picked up a set of these RS4 TBB adapters for use with the metal RS4 throttle body boot. I’m planning on using the RS4 ‘pancake’ pipes, but I want to keep my options open for using alternative setups and these adapters were a limited production run so I figured I’d grab a set while I could.
