Does this sound like injectors or FICM or what

[corey.beggs]

So another post because the truck today on the way home started surging again while drivin down the highway right at my exit so i let off cruise control and couldnt get it to go then it stopped and ran fine. This is the 3rd time this month all under no load comin off the highway. The first time i lost all power but wasnt surging just blowin smoke every where, second time no smoke but surging and p0405 dtc and then this time just surging but with NO codes. I just got my edge insight installed this weekend and it showed/shows nothing abnormal just got sct today and it says nothing. Egr delete is getting installed wednesday. So does this sound like a bad egr valve or injectors or what. Sorry for all the post and for this long post im just gettin really tired of it. Thanks guys.
