Eurotek Tuning News & Updates

APR announced the 2.0TFSI Valvelift ECU Upgrade and Flex Fuel Engines

Posted by

APR's latest tune is the APR 2.0 TFSI Valvelift ECU Upgrade (including Flex Fuel Engines). Vehicles in this category include:

  • Audi A4 (B8.5)
  • Audi A5 (B8.5) 
  • Audi Allroad (B8.5)
  • Audi Q5
  • Audi A6 (C7)

After spending months of development, APR's ECU Upgrade increases turbocharge boost pressure and overall produces more output.  By simply adding in Ethanol flex fuel, enthusiasts can enjoy E85 map blending to yield additional power.

As usual, the Stage 1 tune does not require additional hardware.  Simply get programmed by your local dealer and drive off with additional horsepower and torque.  You'll feel noticeable speed gains immediately. 

By simply installing an approved aftermarket downpipe, one can take advantage of APR's Stage II chip tune (available as a free upgrade to existing APR Stage I customers).

See the tables below.
