04 F-350 with Bulletproofed 6.0
I installed the Blue Spring kit from sinister just as a preventative upgrade. I don't have a fuel pressure gauge so I don't have any data on performance before and after the install. After the install I've developed a heavy bucking when accelerating at highway speeds (around 50-60mph) and it sometimes idles rough, like it may cut out on me while I'm sitting at a red light.
It definitely feels like the fuel/air ratio is now off, and it's really apparent when I'm trying to pull a lot of fuel at highway speeds. Isn't this exactly what the blue spring is supposed to prevent (on top if injector damage, etc...)? Should I just give up and just put the OEM set-up back on and cut my losses? Could my tune (stock performance tune from and SCT x3) be throwing it out of whack?
