Factory injectors, factory rail, AEM universal fpr, precision 3431 turbo factory ecr33 ECU (afaik)
I'm running in the red at NOT on the wideband. If I blip the throttle afr'a dip down to 16 the back to red. It has a misfire- coil pack harness is on the way.

There's only a 4 lb spring in the gate and I'm just trying to drive this thing to a dyno. How much can I increase my fuel pressure at the rail to hep bring down my afr before I start risking damage to the injectors? They were flow tested and are a healthy consistent set. I also don't plan on using these injectors I have another set of DW's
