*NOTE* Hardware upgrades outside of this list will require Calibrator confirmation that a tune can be produced. Do not use Stage 3 tunes without confirming compatibility with Calibrator.
* Rear O2 sensor delete is not available for later 1.8T and 2.0T TFSI and TSI with SIMOS engine control units (as opposed to Bosch MED9 and MED17) with exhaust manifold built into their heads. It's because they depend more heavily on the rear O2 sensor to ensure a more accurate AFR. This is consistent with our desire to maintain OEM-level reliability and smooth drivability, especially at high performance.
