First post here...
I have looked and lurked here for a couple of months but have not seen an answer to my question, ad a search for APR or Chip is not bringing me answers either.
Basically, what I am looking for is advice, based on experience, for the best bang for the buck performance upgrade for my new daily driver.
I am not looking for a compromise in comfort or drivability, just an increase in useable horsepower. Anything in the 260 - 300 hp would be very acceptable.
I have read that APR chips are a good choice but am looking for real world experience.
Thanks in advance for all replies...

 

You dont have many choices. APR stage 2 seems to be what you are looking for.

I was bummed to find out how **** poor the tuning is on the B8's. My 335 had a number of easy to install plug n play potions. The A4 tunes require you to pull the ECU and have it flashed at a shop. The quote i received was 500+ for the tune and 150 for the install. for stage 2 you will need a DP also, i think thats it.
