Ive been chasing down an issue I cant seem to pin point. 04' (late model; icp on valve cover) F350 6.0. Studded and all updates done super recent, egr/cooler delete, 4" straight pipe, bypass oil filter and coolant filter kit, cold air intake, currently on stock tuning on both FICM and ECU. Problem I have is its super slow (almost dangerous) off the line even with a tune on it and only 18psi max of boost. I've replaced almost everything including sensors (needed a lot of work when i bought it). it starts making boost around 2000rpm then takes off but even when it takes off it doesn't take off with the power it should (likely due to 18psi of boost) tuned I only see 22psi of boost max and for some reason 1700psi ICP, stock i see nearly 4000psi ICP. I pinned a picture of my PID's at hot idle. EBP seems high from what I know its supposed to close to the map at idle...? That is also a new sensor as well. I'm just stuck, oh, looked for boost leaks, couldn't find any.
