NO FUEL PROBLEMS!!!
I just talked to Eric at Truckperformance.com and he absolutely assured me that the stock fuel system is ok for the blower. He explained that the computer and various sensor upgrades compensate for the increased airflow, sending more fuel. I already knew this, but this is what I learned: The stock injectors can actually flow more than 19#, a lot more. It's just that the stock computer and sensors limits them. The same for the fuel pump, it can flow more than 60L, closer to 80L. The new upgrades basically function as an electronic fuel pressure regulator, making sure I'm getting enough fuel. If I'm not getting enough fuel, the computer will restrict the output of the engine to protect it. I am installing an air/fuel ratio gauge with the blower, so if I do run lean, I'll put it in the shop for the fuel upgrades. Eric 100% guaranteed that I'll be fine with the stock system, though, so I'll give him hell if I have a problem. As far as he knows, the blower's been shipped, but I'm not holding my breath.
