Default Anyone notice unburnt fuel smell with their exhaust?

I noticed recently that the smell of petrol from my exhaust has became a lot stronger after I chipped my car and changed the exhaust (Abt Stage 2/Oettinger exhaust/FSE fuel regulator). Just wondering whether this mean some petrol are wasted and I should tune down the fuel regulator? Anybody else has the same experience?

Default Search the archives under my name and smell or Neuspeed.


I have the Neuspeed chip, and at full throttle with the roof open I can smell stuff. Happens more with Chevron 92 than with Unocal 92.

When did you chip? It seems to me that it takes few hundred miles for the computer to fully adjust. Maybe it is me, but lately the smell has been fainter.

If you want to, you can e-mail me, and I will update you in a month or so.
