starts and idles but is very rich 10.1 on my innovate wideband
no o2 sensors and no maf
5.3,deka 80s,gt45
what fuel pressure should i be running also?

fuel pressure depends on the tested flow pressure. if they flow 80lbs at 58psi(stock ls) then thats where you put it. If the flow 80lbs at 43.5 psi then you adjust to 43psi with vacuum source disconnected.
fix your boosted pe ratio before you drive this again. set it to 1.276 to target 11.5.
fix your na pe to 1.155 to target 12.6. these tables are separate and dont get adjusted after setting the initial target. do not put boost values in the na table.
bring your high rpm and load timing up to 10-11* bellow 10 causes excessive exhaust heat and some have reported spark blowout.

I’m not seeing a high rpm and load timing , can you point me in the right direction?
I have changed the other stuff
Changed the values and high rpm load and stuff, still having trouble
You probably need to lower the minimum pulse width under fuel tab and lower the min fuel milligrams in transient tab... for too rich at low RPMs and can't get it any leaner

what fuel pressure are the injectors rated for?
min fuel mg could be an issue but you havent given us any information on the injector ratings.

Here is that info I just found and I reset my fuel pressure on the car
Flow rate: 80 lbs/hr, 830 cc/min at 43.5 psi (3 bar
That should help things out.
deka 80s are notorious for overly rich idle issues. Usually solved by what I stated above about min pulse width and min fuel milligrams.

what should they be set at?
Make sure you fill all of the injector tables you can with the manufacturer data (flow rate, offset, min pulse, etc...)

the pressure gets set to whatever the injector data sheet says they have been flowed at.
otherwise stock ls rail pressure is 58 psi and if its not running then you get to send them out for testing or you can test them yourself by commanding them full open in a graduated cylinder for a specific time, recording the results, and doing a little math to find out what their full flow is. then you can steal some deka 80 offset and short pulse data from on the forum to get the rest close.
