My fuel system is for sure up to snuff. I have the riff raff frx installed. Recent fuel filter change, new fuel lines healthy hpop that does not leak, and 8 healthy injectors. It doesnt feel like its running out of fuel when im floored, it smokes a good bit on the higher tunes, i just think my stock turbo setup is doggin me. I need to install my boost gauge i have laying around for sure. I will also add that this morning i temporarily unplugged the red hose from the actuator, started my truck up and it ran pretty crappy, white smoke, and SES light on, just from idling in park. So i shut it off and re-connected and back to normal. I dont see how people gain anything from disconnecting the red line.
