Hi, I'm new here and need some help figuring out whats wrong with my truck. I have a 03 cc f250 fx4 6.0 the truck hasn't thrown any codes but when accelrate hard it will stutter and act like it misses or something after 2500 rpm and higher. Its pretty violent felling like the truck is jerking. If I ease in to the rpm's it doesn't seem to do it and anything under 2500 is fine. I thought it could have something to do with my high pressure oil leak but I fixed that and am still having the issue. I have a sct x4, new headgaskets and arp studs, egr delete, 4 inch exhaust and I'm getting 48.5 volts to ficm my hpop is putting out 2800 to into the 3k's. I can rev it in neutral to in the high 3k's then it sounds like it hits rev limiter. Any idea's on what could be causing this?

Did you try cleaning your turbo?

You should check you icp number under load instead of neutral. Not sure if it will change anything but it's worth to try. How's the fuel pressure?
