I just had my up pipes exhaust manifold and egr delete done the truck ran amazing brfore now its over boosting and cant get up to speed in stock mode. Im doing the map and ebp sensors later any othere ideas im new to diesel

I'd start out by pulling the EBP sensor and tube and cleaning the tube out. Blast it out with brake clean/carb clean etc. See if that helps. 6.4's (specifically with egr mods) tend to get moisture in there and it freezes causing the back pressure sensor to get false readings and changes vain position resulting in the over boosting. Thus resulting in over boosting issues. Start out cleaning the tube and go from there.
