Hey all, I have a 2005 A6 C6 4.2 quattro and have been wanting a ECU tune and an exhaust I've been talking to my service advisor at the dealership threw this company called stasis engineering and the service advisor said that 05 is a split year and she needs to know what the stock hp is of my car is. I looked around and found that the 4.2fsi had two ratings 330 and 350hp.
My question was is there a way for me to tell which motor I have?
Thanks in advanced

 

the engine code should be on a label in the spare tire well

you can also tell by the VIN number. not sure what the split is on '05 A6 though
