We show basic details only for this EO. Its vehicle list is not a ruled table we can read reliably (often a scanned table or a list in the text), so we do not copy it. Check the vehicles and part numbers in the original PDF.
What the EO says about the part
The Delta Boost Performance Tuner Module consists of a control module installed in series to the vehicle's Electronic Control Module (ECM) and the user is able to choose from four different percentage settings to vary the amount of a pressure sensor(s) output to the ECM. No other changes are required for proper installation. There are no user adjustment to emissions related data files.
