Okay, I've got a 383 HSR, and I've converted my ECM to '730 (speed density). I'm running 28 LB/HR LS1 injectors and have my fuel pressure at about 58 PSI (which is what is required for these injectors to run at 28 lbs). I've set my injector constant in Tunerpro anywhere form 23 lb injectors all the way to 32. It STILL says I'm running rich. I've adjusted the fuel pressure all the way down to 40 PSI and the car barely runs, but the O2 still says I'm running rich.

I've already replaced my O2 sensor and checked my MAP sensor. Is there anything I'm missing? Since I'm running a HSR, do I need to disable EGR in Tunerpro? I'm stomped on this one as my car sometimes spits and backfires, although the ECM says I'm running rich. Could my ignition module be bad?

I really need some help on this one.

 

You need to work with the VE table.
Set the injector constant to the correct value, and start working on the VE table. Then start optimizing the spark.

 

 

I had to do some tuning on the AE tables. It works great now. I increased the "Enrich Accel Delta TPS Pulse Width Factor Vs. Temp" and the popping is gone now. Now on to the Spark Advance Tables.
