Aftermarket fuel pressure regulator? Is it operating at a different pressure than your tune is designed for? If you're running a stock or Stage 1-chipped ECU then your fuel pressure should be 4bar. If your fuel pressure is something else then that could be a problem.
An old primary (pre-cat) O2 sensor will cause a richer mixture, so that could be another possibility if the previously-mentioned isn't true.

This forum is pretty amazing too, but we can only help you as much as you are willing to be helped.

Disappointed by the truth? There's a couple handful of guys on here that are knowledgeable, everyone else just bought their car and is just learning. Vortex and the Zine have a lot more people that know what they're talking about, generally.
