When I really step on it and let my truck rip when I let go of the gas there's like a studded I have know idea even were its coming from its like it wants to keep going its sounds like a semis Jake brake or something I have to burp the gas peadel a couple times to get it to go away..does anyone know what I'm trying to describe?? And I think it's gotta be hard on the truck..

Without hearing it for myself, I would say you are barking the turbo which is not good for it.

The only way to stop turbo bark that I know of is to install a blow off valve or ease out of the throttle rather than suddenly lifting.

My truck does something like that when I beat it on it heavy on throttle then let off fast. Its because the vp is hsving trouble keeping up with the call for that fuel. When I let off quick it sounds almost like it has a lopping in it from a cam or lope tune. Try not letting off the go pedal so fast.

what are your mods. Many of the programmers fuel really hard and when romping on it, you let off fast the truck does funny **** either doesn't wanna stop fueling for a sec or shutters or you can be experiencing turbo bark wich is not good but way worse on a said stock turbo than a built turbo according to a lot of companies my big aurora used to do it with my smaller sticks when i let out but now its building more boost and it doesn't do it anymore.
