RE: best chip
I also went with the APR direct port programming. No pulling of the chip and invisable to the dealer (so they say). Easy to switch between programs, stock, 93 octane, 100 octane and valet. All through the cruise control stalk. Takes about 60 seconds to switch programs. I have a 2003 225Q. It makes a BIG difference. APR claims 267 HP on 93 octane and another 20-30 on 100. I'm not sure what is available for the 180. APR website is www.goapr.com. Max turbo boost has gone from 15-16 max in stock to 20-21 running the 93 program.
