ER34 GTT and Siemens Deka IV 60lb

[DistSynth]

Hi everyone!

I'am stuck with my tune and need help

Specs:
RB25DET NEO
Holset HX30 turbo with tial wastegate (wented to air)
Z32 MAF
Greddy like intake manifold
HKS SSQV
Aeromotive fuel regulator
Tomei fuel pump
Siemens Deka IV 60lb/630cc injectors FI114961
GTR intercooler
Innovate LC-2 wideband oxygen sensor (connected to ECU like narrowband)

In my tune:
K - 581 (i set it few yaers ago, before injectors was installed)
TID - 54431
Injection latency - 1000 (but in injectors spec it must be 640us)
O2 feedback is off

If i set latency to 640us AFR is about 17-18.
On idle AFR can be between 14 and 16. Car can stall after 0.3 Bar of boost (if boost will be 0.7 Bar car stall 100%), but before i install injectors all things was ok.

I would lower the latency for those injectors down to about 700uS... as that seems rather high for that size injector

What is cruise AFR like with those settings?

[DistSynth]

AFR on cruise is about 13.5 — 14.
I think it's too rich.

You may need to increase TID further to make it run better

With NEO engines there is no Min TP table, so sometimes I increase the lower end of the VQ map to add more fuel around idle
