Do I need to adjust fuel mixture?

[4to8m8]

Just had a Fabspeed euro pre muf and max flo sport exhaust installed. Now that there is no longer a cat are there any adjustments that need to be made to the mixture? Father in law says he smells fuel and that it should not pop during decel?

I had to adjust my mixture (lean it out) after replacing my cat with a pre-muffler. That took care of my excessive pop during decel.

Lack of Cat will make the exhaust smell richer. The muff will also cause a slight popping. If its not overly bad, leave it. If you are concerned, the best thing to do is to take it to a shop and have them do an exhaust gas analysis. The only thing worse than running a little rich is running too lean and burning a valve.

Do a search on how to set your mixture by measuring the voltage output from your 02 sensor. That's how I set mine.
