2015 6.7L Powerstroke, EGR and DSP Delete, cutting power above 2500 RPM

I.ve deleted EGR and DSP for a Off Road Truck, I have the EGR table "0" and all Diag related on "Disable". didnt change anything else until I learn Diesel tuning, witch is my first, so my goal its make a little more power but not crazy, just safe so I can use the truck to pull a trailer with a race car inside on weekends.
The truck drives good in low rpm, if you kick the gas it goes strong and quick on 1st gear, then it shifts and get lazy above 2500RPM like no turbo pressure...before the delete was fine. after the Delete, pop up the message "Engine Power Reduction" and with the EGR data tuned it didnt came up anymore, BUT still lack of power above 2500 RPM...Where to start tuning now?

PM me.

I'm having the same issue. Sent you a PM. Thank you.

Just EGR?

New to the tuning world and eager to learn. I'm trying to do an egr/def delete on a 2011 6.7 power stroke. mostly used for farm use, hauling fuel tanks and such around any chance someone has some files I could look at so I don't go into limp mode right out the gate?

Wont be able to with hptuners platform.

it seems ford has some built in logic that cuts power around 50mph with egr removed. no other changes to calibration other than egr turned off. only code that comes up p2425. with diverter valve disconnected truck will do 20mphs no matter how much you push the pedal.

There is no ?logic? that does that.. there is something in the tune that isn?t right.

Literally 1000?s of trucks out there running perfect.

SO what i am seeing is a boost issue, during acceleration i can get up to about 50mph, and boost does not a get above 10psi. I am not sure what i am missing.

is throttle valve disconnected?

Yes, the throttle valve is disconnected. what i have applied i still receive to dtc P2456-00 & U059E. I would assume the file i applied would have turned that off. everything is as far as fuel and torque tables are all stock. TCM is also stock. I was thinking about doing an emission relearn using my scanner?? any help would be greatly appreciated.

egr has to be disabled in the xdf file. or else it will go to limp. just killing the code wont deactivate egr.
