The factory turbocharger on the 2.0 TFSI EA888 Gen 3 engine is highly capable, but as you increase boost pressures with a Stage 1 or Stage 2 remap, the factory supporting hardware quickly becomes a weak link. Upgrading your turbo accessories ensures your engine holds boost reliably while allowing you to monitor critical performance data in real-time.

Turbo Dump Valves: The factory plastic diverter valve is notorious for tearing or leaking under increased boost. Swapping to an uprated piston style turbo dump valve ensures your engine holds maximum pressure safely, while also giving you the option to unlock that signature vent-to-atmosphere (VTA) sound on lift off.

Boost Gauges: Keep a close eye on your engine's vitals. Installing highly accurate boost gauges allows you to monitor peak boost and vacuum levels from the cabin, helping you quickly spot potential boost leaks before they cause serious performance issues.
