Before we get into the whole PCIII is a waste of money and you should use TuneECU or Tuneboy. I have done that. I have an 04 s3 with the TORS high mount and a K&N air filter. I installed the TuneECU map for the can but my s3 still wasn't running right. Continued to have a blueish, whiteish smoke coming from my can. No, it wasn't oil. Had a super lean smell coming from the exhaust. Afraid of burning up my valves I had a PCIII installed and dyno-tuned. Having a friend with a shop and a dyno is a slight perk. Anyway, tuned with the PCIII the bike runs great and would do it again in a heart-beat. However, over the last month of seemingly constant rain someone unplugged my trickle charger and my PCIII went back to factory settings. Does any one have similar mods and that check their PCIIIs levels so I can ride today. My buddy went down the shore and my map is at his shop. Thanks in advance!
