im having problems with the engine getting fuel, i just replaced the ignition module and im running a 88 iroc TPI with the l98 350
i had the chip tuned for the lt1 injectors, did away with the smog system and egr. and i have a remote coil distributor. what would cause it to cut out when ever i lay the hammer down and not when i take it easy. i have a BBK adjustable fuel pressure regulator, fuel pressure gauge, and high flow Bosch fuel pump and new fuel filter, and its tuned about 50 lbs. i have no clue whats going on, or what would cause the fuel to just cut out. any help would be great. thanks

 

Change the fuel filter lately?

 

What's your fuel pressure when it bogs?

 

the gauges are under the hood and it happens erratically, it has happened when i stomped on it from a stop, it happened when i was slowing down from 45, and it happened when i was cruising at 65. i have tuned it sitting still in the driveway and brought it up to 5500 rpms and it doesn't lose power. and the fuel stays at a constant 52-55 lbs. i replaced the fuel filter about a week ago.im running a stock coil and when it happens i can use starter fluid and it will start and run for a min. could my fuel pressure regulator diaphragm need to be replaced? could the spring be worn out and dropping fuel after it reaches a certain rpm after being driven for a while?

 

Are you using a pressure gauge with a hose? Tape it to the windshield and take it for a ride.
