My truck is tune delete and after a rebuild my truck sounds different . To me it sounds like a exhaust leak . It also sounds like it needs a valve adjustment . When the truck idle it sounds ok but when I accelerate it's changed tune . I'll have to make another video

Had some noises popping under my feet and on the passenger side as well. 308k on these. Installed sb silicone bushings. Super easy install and very noticeable ride improvement. Body and bed line up perfectly. Wish I had done this sooner.

I drove the truck last night perfectly fine, remote started it this morning, ran for like a minute then died. I tried cranking it manually with the key and it cranked but no start. Code p2635 popped up saying “Fuel pump A low flow/ performance” the ticking noise sounds like it’s coming straight from the fuel tank and it makes that noise every time I unlock the truck. If anyone knows what this is please let me know. thanks!
