I dont understand how my a/f gauge(blinky) is staying in the lean are, and my wideband is reading 11-12. The ecu is seeing something to mAke it lean and in turn dumping extra fuel causing it to be rich and my wideband to read 11's. I have replaced the map sensor, or sensor, plugs, wires, and i still cant get it right. My setup is the portfueler with stock primaries, aeromotive afpr, inline pump, and in-tank pump. I have the power wire disconnected since i wanted to make sure it wasnt that. I cant boost cause when i go wot(when portfueler was connected) my wideband reads "rich" and i understand that since it is rich at idle. I am lost and am pissed since it is one thing after another with my car. The car was running good a couple months ago before i start to rebuild everything. Any suggestions, i tried to look in the search and that where i started to replace everything. Thanks.

I think it is this also, so gonna replace it soon, once that is fixed i can boost and tune for 24psi. So wish me luck. Thanks for the replies.
