Turbo Cough

Hello all. I just put my truck back together. Installed an EGR cooler with plugs welded in the ends and rebuilt my turbo (with the Garret rebuild kit). Everything seems to be running fine, but I hear three "coughs" whenever a quickly release the throttle during a hard acceleration. Is this extra boost getting dumped off or something else? It did this before I installed the new EGR cooler as well.

It's unused air coming through the turbo. Fairly common actually my truck does it terrible if I chop the throttle.

Yes, very common. Is also very hard on the turbo. Picture your turbo spinning close 10,000 RPM then all of a sudden the flow thru it gets reversed. Think of it like your auto transmission being thrown into reverse as your driving down the road.

LOL. Actually it's really called turbo surge but turbo fart sounds better.

Or maybe a whole new turbo and injectors. IDK Easier just to not back off the throttle fast.
