Datsun 510 guy

This screenshot is of my NA6 turbo base map on a Haltech Elite 750. The steady state AFR is at the target is all the cells where VE < 30 but this sure doesn't seem right, although the car runs/drives just fine. It's an internally stock fresh rebuilt NA6 with a little GT2554R turbo. Injectors are Injector Dynamics 1050x. The map looks to me what I'd expect if the injectors were bigger than what I have specified.

My only thought is when tuning the base map should O2 control be disabled? Haltech's documentation is good at saying what a setting specifically does, but they give no context of "if doing this, don't do that". I kind of refuse to believe VE is so far off a stock NA6 seeing as off boost it's...a stock NA6 with big injectors.

What's borked up here?
