Since I’ve been spending a good bit of time underneath the dashboard wiring up various sensors and gauges I decided to take care of swapping my aluminum trim back in the car as well as the black surround of the cup holder and hazard button.
I completed the wiring for the Fuel Pressure Sensor and gauge and they are now operational.
Getting a bit more organized, I made a panel to hold some of the gauges I’m using for various measurements.
This dyno shows the TTE550 turbo’s on a B5 RS4 versus baseline data on the same RS4 with the RS4 K04 turbo’s.
I find these results very encouraging as I look for a turbo that is similar to K04’s in low end torque and able to take full advantage of the stock S4 motor limits.
The scaling and units make interpreting the chart a bit challenging for me being accustomed to U.S. units at the wheels, but the curves showing similar low end response and significant delta that the 550’s put down over K04’s are unmistakable.
