S-AFC 2 Installed.....now problems

[Firefox2003]

Ok, so today, I hooked up a S-AFC and a A/F Ratio Guage. All the wires are right, did the initial set up, have everything right. So I go for a test drive.....and at higher rpms, it's like i'm getting Fuel Cut. My Autometer boost guage reads 11psi, the stock one reads 14psi.....

I bought the S-AFC off a friend, who got it off DSMTrader.com, and it was previously installed on a DSM.

I have a 90 Tsi AWD.

So what do you guys think the problem is?

Thanks, Cody

Whats the knock count showing? Maybe you need to add more fuel. It would also be nice to know your setup.

Ok, well all the values are at 0. I'm running really rich also? Like Black Smoke cooming out the exhuast...not blue or whitish that god. So maybe it's my car bogging out? What would cause this? It ran just fine before the S-AFC was installed.
