LMM: Vibration/buzzing sound

[buildingup]

As I mentioned my LMM has this odd issue I have never experienced. During forward momentum with medium to heavier throttle there is a buzzing/vibrating happening that I feel in the pedals. Also, when I put the truck into reverse it starts happening and I feel/hear it in the pedals. Haven't had time to run over to Merchant auto or Burkharts shop.

Could this be something to do with the torque converter or something else on the truck? Starting to get really annoying and makes me drive the truck worse then grandpa.

Check and see if the drivers side boost tube is touching the master cylinder under load. Mine is pretty close. On edit, just noticed you said LMM, it still may be the problem, I dont remember how close the boost tube is on an LMM.

This was EXACTLY what the issue was with mine! It was vibrating the pedals and your feet just as you described. I put a shorter boot on the boost tube to turbo to suck the tube closer to the motor and get it away from the master cylinder

Will take a look at this today. If this is the issue where can I pick up a new tune from out can I cut mine down slightly?

You dont need to cut it. Loosen the clamps and shove the boost tube toward the turbo and retighten the clamps.

You may need to move the clamp on the boost tube side towards the turbo also. My boost tube kept sliping towards the master cylinder until I sliped the clamp further on to keep it from moving.
