With or without boost, at random throttle levels the car will hit really hard and power will cut out. It sounds like the throttle blade just shuts, the boost goes all the way down, and my O2 readings go very low and sometimes get very little knock when in boost. If I roll into the throttle it doesn't do it as bad or frequently. It seems to happen the most when I just smash the throttle. Fuel pressure is good and climbs 1:1 with boost. I taped my phone under the hood and when power cuts out the fuel pressure goes back down to idle pressure. I am at a complete loss, here is everything I have replaced checked... -Plugs (ur5 gapped at .035 new) -Wires (MSD new) -Type 2 Ignition coil/module (both new) -Crank Sensor (New) -Cam sensor cap appears good, metal ring is solid (does not spin), car runs the same in batch fire with casensor unplugged -TPS (New) -MAF/MAF translator (New) -Injectors OHM good -TT 5.7 chip -Accufab pressure regulator (42 line off pressure) -Walboro fuel pump with hot wire kit If fuel pressure is steady and rises with boost what would make my O2 output drop so fast? I have a scanmaster but no data logger, What are some outputs I should check? I have been all over the forums for weeks and do not know what to check. Thank you for your guys time.
