I have a 2010 turbo 5.3, 76mm turbo, 16 lb's, boost cam, 83 lb's inj, and exhaust.
With my flex fuel pump i was running out of gas at 5k rpm's fuel pressure was dropping around 32 psi. I switch to the walbro 450 and now the fuel pressure drops to 38 psi at 6k rpm's. What can it be that my fuel pressure its dropping? Should i change something on my desired pressure table?
I been searching around but haven't found something to make the truck work. I don't want to mess with the desired fuel pressure before asking someone that know and have mess with this tables, I've files that are change settings on the desired fuel pressure table.
Here's the file and a quick log of the fuel pressure.
