I just talked to Tuan after sending my unichip to him because my car is running dangerously lean lately. He mentioned that even with my modifications (test pipes, nismo exhaust, APS plenum) I shouldn't be running as lean as I am right now (12.5-13.0 a/f ratio in the higher rpms) and we narrowed it down to the fuel system. Whenever I would fill the car up and park it in my garage, the garage smelled like nothing but gasoline like there was a leak somewhere but I could never pinpoint where it was coming from.

To make a long story short if anyone who has a TT kit (especially APS) can direct me to a shop near the Atlanta area to have this checked out I would surely appreciate it. I'm going to contact CPRace as well to see if they can fix it.

 

Umm, so you are lean but all you can smell is fuel? Am i missing something here? 12.5-13 A/F? Isn't that not lean? For my N/A settup it's just about right. I don't know as much about FI though.

 

yea for F/I that's considered a bit lean. Mine is at around 11.5:1 to be safe.

Good luck man. Might wanna post in the forced induction forum to get more helpful replies.
