Question 6.0 wont run past 3000 rpm

2004 F250 6.0PSD - 2004.25 engine. I have had numerous cold start problems in the past few weeks, ran batteries dead cranking. I replaced both batteries with 930cca dry cells. She cranks all day now just fine, especially if she is plugged in then no problems. However, I didn't obtain a "pluggable" parking spot on saturday night. Sunday morning I started the truck for about 6 minutes. I let it warm up to 145 on the commander display then headed out. Drove fine until I tried to accelerate onto the highway. Power dropped off after 2500 rpm, and dead halt at 3000rpm... Standing on the throttle had no effect. Shifts were harsh and delayed. It seems fine until the tach approaches 3k. I have a quadzilla xzillaraider installed, commander monitor, 4" turbo-back bullydog "no cat" exhaust and a disabled egr + plate removal. The hard start issues seemed to arrive in parallel to the performance upgrades, even in 80 degree weather it started slow. The egr delete was done after I noticed the hard start and that fixed the stumbling after cleaning wouldn't help. Does anybody have any ideas? I have the truck in for service, just want to be prepared for what they have to say. Any help is appreciated. Thanks

I replaced the fuel filters about 5000 miles ago. I am running Powerservice anti-gel/ injector cleaner. Maybe, it is also cleaning sediment out of my fuel tank, any truth to this?? If it is only my fuel filters, that'll make my day.

Welcome to the org.
Have you checked for any codes?
Check the obviouse stuff...all filters - especially air - oil and filter etc. Check for codes if you havent and report back.
It does sound like a fuel starvation issue but air could result the same i believe. Maybe have your fuel pressure checked at the dealer. If your starved for fuel pressure you'll want to take care of that before you ruin some injectors.

2003 6.0 F350 dually on high cholesterol fuel (WVO)
2000 7.3 Excursion also on a high cholesterol fuel
