not enough boost with new tuner

I have a 2008 f250 and it has a dpf and an egr delete on it as well as an afe intake and an sct livewire with innovative tunes. The question I have is where is the egr pressure sensor located on this truck? I cannot build over 30lbs of boost and my truck lags pretty bad when you stand on it as well as the unforgivable dyno numbers I just recorded. I put an egr delete on my buddies 6.0 and it still lagged in the same sort of scenario so I looked into it and we found the problem to be the exhaust pressure sensor, so I was wondering if it would possibly be the same sort of scenario on my 6.4 where I could clean it or replace and solve the problem. Thank you for taking the time to reply before hand.

Take off your map sensor and ebp sensor and tube and clean them. I replaced mine just to be safe. That would cause boost problems. Here are pictures of where the sensors are located. :thumb:

I replace those sensors once a year now and it does make a difference
