loss of power after egr delete

i Just finished up a egr delete up pipe and oil cooler and ec-1 on the truck, drove to work for a week, then went camping. the trailer weighed about 9-10,000 lbs and i could not hold 65 mph, felt like i was pushing it hard to stay at 60mph.

This was stock tuning. i have always had a tow tune on the truck before when pulling this trailer but i refuse to belive stock tune would be this powerless.

Truck is a 2004 f350 6.0 has full 4" exhaust, warren diesels 155 injectors, blue fuel spring, 6.4 banjo bolts, cts

Also before the temps were around 190 with a 10 to 25 delta. now after the egr delete and oil cooler the temps are 200-230 but deltas are always 10 or under

I have checked for leaks and found nothing, egr has been unplugged for a long time so im sure its not that. boost did go down to 22 but i hear that is normal after a egr delete

sorry for the long post but any help will be greatly appreciated.

also to add while driving with no load it feels like it should for being stock. although while on the freeway in overdrive if i give it a little gas to speed up it seems kinda gutless until it downshifts

May be having a couple issues perhaps the FICM is faulty and you have blown egr cooler and headgaskets causing the leaking coolant

make sure the up-pipe does not have any leaks and your cac boots are on and are not leaking. After a egr delete there have been alot of complaints about no power after its installed.. Check those listed item for sure.

the cac boots are hard to check on truck.. You need to take them off and clean them up real good and inspect them.. An exhaust leak will be easy to find, craw under truck and look at firewall- if there is black soot etc, then u have a leak.. You have a monitor? The injectors would be next on my list to check

hooked up to the trailer today to see what it was doing and as soon as it goes into overdrive boost goes to 1 psi and stays there while giving more throttle until it downshifts then back to 10 psi at least. when in overdrive shouldn't i see more boost then 1 psi
