Low power

I have a detroit12.7 egr engine that was deleted and tuned to 550hp with 1850 torque non wastegate turbo(borg warner171702)truck doesn't have goodpower when going through gears sluggish 9/10 gear falls flat hit a small hill or incline it falls back can't accelerate pedal goes to floor and does nothing until I crest the hill, runs ok on flat ground all of that with truck bobtail, empty or loaded,I changed injectors from stock 7860 to 5915 to flow more fuel but didn't make a difference the guy that changed them out said he set all them to .75 Don't know if that's right need help!!!!

 

Which actuator? I deleted the egr system completely

 

Which actuator I deleted the egr system completely

 

25-28psi 30 if I push it

 

Maybe but I put a new pedal assembly with sensor on it but a tech said the wires were wrong so he rewired it because it wasn't getting the 100%value when depress on the laptop

 

I have a non wastegate turbo so there's no actuator
