get a fuel pressure gauge and connect it to your vehicle record the fuel pressure at idle, during take-off and at cruise. Post those pressures here or compare them to specification (sure you can find them online).
Might by low fuel pressure (clogged line, leak, ect).

However, if you want, you can clean your EGR by removing it from the egine and cleaning it with carb/throttle cleaner. also clean out the EGR intake ports.
