How lean? What is the wideband reading?

10.0 lean and yes aem wideband

 

[mygsx2120]

10.0 is rich, not lean. Big difference

how is a rich situation even possible with stock injectors and a 16g and fpr set at the stock 37

You're running leaner than the factory fuel map is targeting (9.x:1 AFR), which is expected on stock injectors and flowing a bit more air.

It's rich in the terms of AFRs though (9:1 is rich and 18:1 is lean).

Aem widebands peg rich at 10:1. He probably has a boost leak.
