I have a 99 suburban I put an ls 6.0 into with 243 heads and stage 2 btr truck cam. it has a TBSS intake with a WARR throttle body. When I first started it, it fired right up and idled (really rich) but started fine. I have since removed some fuel to get it closer and replaced the fuel pump with a Quantum 340 lph unit, The regulator i am running is a holley fuel injection regulator and its set to 50psi. On initial startup it was at 40psi. Now its really hard to start. I have to prime the fuel pump numerous times to get it to start. I can hear it popping in the exhaust when i am cranking and if I hold the accelerator at 100% (flood clear) it will start and run. After I get it to start and run it idles fine. Has a hard time restarting as well. Any idea where to start? not sure if I am overfueling or maybe have a stuck injector. Attached is my most recent log and most recent tune. Still working on getting a wideband as that is a separate issue I am working on with AEM.
