[QUOTE="gnxtc2, post: 1074514, member: 1414"] For the past few weeks when I'm cruising, I am getting a surge. No drop in rpms, no boost change.....just a surge. I changed my fuel filters as a precaution. Well this evening when I was driving home from my shop, I was pulling a small incline. Then all of a sudden, the motor starts bucking, like it was running out of fuel. I would occasionally surge for the ride home. I get home and I look under the hood at fuel pressure gauge. I have a fuel pressure gauge to mount in the pod but haven't gotten around to it. Fuel pressure gauge said it was 40lbs. As it idling in my driveway, it's surging/rpms changing. Thinking it a wiring issue, I wiggle the wires by the relay...no change. I adjust the fuel pressure regulator to 65lbs. I believe I have a Phoenix fuel pressure regulator that came in the E-Fuel kit from DynoProven. Not saying that it's DynoProven fault, any feedback on the Phoenix regulator? I am running a SD Fuel pump that I bought new. It has around 12K miles on it. I don't even hear the fuel pump run if that means anything. Thanks Billy T. [email]gnxtc2@aol.com[/email] [/QUOTE]
