Weak acceleration from stop
My 2005 6.0 is exhibiting a weak acceleration from dead stop. It’s so bad that I would be scared to not be able to get out of the way of someone if I needed too. Once it moves about 4-5 seconds with rolling on throttle the turbo will spool up and power is as should be. I don’t remember the exact RPMs that the turbo finally powers up but I don’t know what to look at. Please provide me some parameters to monitor and I can get you some data.
Truck is EGR deleted if that helps.

Post data for the following @ KOEO (key on engine off) and then take it for a spin and show us some numbers while you're accelerating from a stop.
FICM MPower
FICM LPower
Battery Voltage
VRef Voltage
ICP
ICPvoltage
IPR%
EBP
MAP
BARO
VGT%
Would also like to see fuel pressure - that does require an aftermarket sensor of some sort as the PCM doesn't monitor that on these trucks.

I need to try and pull the data from my tuner data log but I did note that when I have the pedal to the floor, my ICP is barely climbing till about 1400 psi and then that’s when it will take off and turbo spools up. It does have a bigger turbo on it. Not sure the size. Also at WOT my IPR is like 87
