Tuning issue or too big injectors?
Hi,
I take some winaldl logs at idle(750rpm) last saturday and noticed that injector pulse width(bpw) was only 1.2-1.3ms,and integrator was from 92 to 102.BLM was 108.
At first logs intergator was at 85(fuel pressure was 43psi)After that I lower fuelpressure to 37psi,and then I got INT 92-102.Engine have 30lbs FMS injectors.Are those injector rated to 30lbs at 39 or 43 psi?
Engine is sbc 355,vortec heads,stealthram,hotcam,tri-y's no cat etc.Ecm is -870 with lsracingchips tune.

You might post this in the DIY Prom board... they focus more on winaldl logs, readings, etc.

Looks like you are running way rich. You need to lean out the fuel tables.
