Motor bogs down after 4-5 secs of full throttle

Clueless and frustrated I took the intake off and looked at the knock sensors, and hopefully streetstalker led me in the right direction. I found a piece of one of the connectors laying up against the knock sensor. Unsure if this was making it do it or not but I sure hope so. I checked both knock sensors though and they both were withing the tolerance 99.4 on one and 99.9 on the other, they both also moved up when i tapped them. The harness was also good, so back together it goes now and hopefully it works now.

Hey man, what did you find out? When I installed my motor I put in new Knock sensors and harness. It still bogs down, same as it did when I just installed heads and cam, then I installed a new motor and it did it, then I installed bigger cam-injectors-TB-Intake-walbro fuel pump and it still does it. Needing some help if you found an answer.

I put in a Monster Transmission, 4L60E with a Circle D 2800 converter during the 2nd motor swap. It's weird because it doesn't bog on the dyno, only on the street. I also have a FULL tank of gas, 34 gallons worth!
It bogs at the 1-2 shift and it has done it a couple of times on the 2-3 shift
