Just curious if anyone has run into what I ran into, so I have after market Injectors.. 950/1800 and I had been running 45 to 46 lbs fuel pressure. For the most part, no issues... But occasionally under light to moderate gas pedal modulation, I would experience dead lean...like there was no fuel at all. If I let off a little on the gas it would come back to life. So , I thought... Bigger injectors probably need a little more fuel pressure. Well the problem got worse with 50 lbs pressure, so I went the other way and backed it down to 42lbs...and that cured the issue, I am not sure why...was thinking maybe the more pressure created void or air in the injectors... Don't know. I thought I would share this, perhaps someone else is experiencing this.
