The tee is what I'm picking on at the moment. If you hook it up the way I think you would, it would allow high pressure fuel (shown in red) to flow unrestricted back into the tank. You would build very little pressure in the fuel rail. I think you'll run very lean then.

Next on the list is the little silver regulator with no vacuum hook-up. That will only allow you to set a static fuel pressure that does not change with boost. Unless you want to flood your engine at idle, you could only use it to set a minimum fuel pressure (pretty useless). In that case, the cartech would only add fuel pressure on top of that (putting you in no better position than you are now).

If you knew what your fuel pressures were, you could probably trouble shoot your lean issue. It might be that the cartech does not have a high enough gain for you (especially if you set your static pressure super low to keep from running pig rich at idle). It might be that your fuel pump cannot flow enough fuel at the pressures you are running.

If you read through the wiki, you will find several articles about fuel system setup. That might be helpful in understanding how you have your system set up and how you need to change it.
