Default F250 gas or air problem idk

Hello everyone, im having a gas or air problem im not sure. Ripped off smog and blocked off egr and replace map sensor. But still having a problem when i accelerate without feathering the pedal it will bog out and or back fire. I have to give it a lil gas and let off and its like it just opens up and runs great until i come to a stop and or going up hill. Runs great when cold but when she warms up idk just starts boging out and if i try to put the pedal to the floor to you know down shift and open her up she backfires and doesn't go anywhere. I'll take any advice or knowlegde i can. Thank you guys for your time.

Hi Josh,
It sounds like you have an older year Ford, but we need to know what year and why are you disconnecting / removing certain controls?
How many miles on it?
What engine do you have ?
Anybody play with the dist?
When were plugs last changed?
What about wires?
Give as much info as you can.
