Ok so currently my car is running lean . Few things to note . Car is RS enapthy tuned . Fuel pump is hardwired to the battery . 550cc injectors prior having problem I decided to buy new injectors . The old ones I had flow tested and cleaned and two of them are bad . Got new injectors now . Cranked it up immediately noticed a difference in AFR was idling steady at 14.9 15 . The following day I start it up and it's back to 16.1 16.9 . Also the distributor timing is off . It's on full retart .i will go about changing it back to between advance and retart but is there any other steps or tips that you can think of I would gladly appreciate it . I also will be checking for fuel pressure . The car runs a factory regulator

What is the afr when actually driving?

My KA-T at idle is around 15 or so.

Currently at idle it's at 15.5 15.9 . It got little better I had a little vaccum leak . My tps is also acting up so I'm going to dig into that . But in throttle / boost probably 13.7 14 . How's yours in comparison?

In throttle/boost you should be around 10-11 with an enthalpy tune they're extremely safe.

I have mine pulling 3% fuel with an SAFC Neo.

This is as spot on as it gets. I think the most you'll see is maybe 11.7 ?

Not near the car right now going to check my tps and and any other fuel related components and update you guys . In boost i think I might be off cause i recall it being 11 most of the time I look at the wideband .

was there a difference in RPM at idle between AFR 15 and 16.9?

No change in rpm maybe a hair of throttle from messing with the distributor but that's it .
