NVR tune on dyno:
With my conversion over to RS4 K04’s, RS4 MAF sensor, and Bosch 72# EV14 fuel injectors I looked once more at how the modeled EGT’s compared with the readings from the RS6 EGT sensors.
K04 Stg3 tune on Street:
With this setup on the street the modeled temperatures are becoming less accurate. The mid-range modeled temperatures exceed those recorded by the sensors.
