Custom built multi-function digital boost gauge and more for the 8Y generation (2022+) Audi A3, S3, and RS3, including 35 TFSI, 40 TFSI, 30 TDI, 35 TDI, S3 2.0 TFSI, and RS3 2.5 TFSI quattro models.
We designed the P3 Gauge to read the most important data from your specific vehicle for easy plug and play install. You'll get everything you need with a single OBD port connection to be up and running in minutes. If you wish to add additional sensors, or not use OBD at all, advanced tuners can use analog inputs or even run in "analog only" mode.
