I Need Help! A/F off the chart lean!

My boost is set at 20psi. No matter what I set the fuel numbers to, it does the same thing. This is worrying me. Thanks.

Was your reading just one spike in the AFR or was it continuous?

It was continuous, but I figured out the problem. I started using my brothers computer, which didn't seem to work well with the ecu+, so I went back to my original computer. A glitch caused the upper clamp to be set to something like 1000Hz, so that is why there was no fuel cut, and I was running out of fuel. It's all better now. Thanks
