Default Multiple newbie questions

Hey all,

im running the terminator x ecu on a 6.0 Ls kinda trying to figure a few things out and I've searched a bit as well before making a post.

so I ran about 120 desert miles today and started noticing in low rpm 1-2 gear low 2k rpm area my A/F has a wierd blip where it shoots ip to 16.0 and sometimes even higher. Normally it's around the 13.0 area . So it studders and try's to die out. It only does this in this rpm area.

so here's where I'm at and maybe I'm leaning toward the wrong direction here.

my map isn't listed in the config area (09359409)
do I just select the Holley internal 1 bar ? Also am I messing up by having that vacuum line connected to the Holley and running that map sensor ? Do you run one or the other?

Other question my injectors are listed but online I can't seem to figure out if they are a 43 or 60 psi system. Or does this even matter ? (25317628)

my regulator is 60 psi but I haven't been able to confirm that I'm actually keeping it even getting 60 psi.
it's a cheap Chinese corvette style knock off.

so with this info does it sound like I'm on the right track or am I possibly just missing the mark entirely?

What kind of fuel are you running?? What base tune did you start out with?? Is this just an NA combo?? Speed density or VE based?? Select the internal map sensor and run a vacuum line to that. That injector(25317628) you've listed is in the drop down menu of preconfigured injectors so just use that, this is assuming you're on the V2 software.

Check your fuel pressure to be sure that you've got proper fuel pressure. Try to pinpoint(Datalog) where that little blip in your afr is happening and manually add/remove fuel from that area to see if it cleans up. I had a similar issue with my Dominator on decel around 2800 rpm and 4% tps it would go lean to the point of wanting to die, I removed a bunch of fuel and no more of that
