unless ur running big boost it makes sod all difference. The jerkyness is also due to the tps being a basically on off switch as well im pretty sure.

loads of people dont use dump valves and im sure their turbos are fine to be honest.I will be taking mine off as soon as i go efi, get the chatter on the go, sounds a million times better.

same but then again ive got friends with turbo cars and their turbos last ok given the abuse they get. I dont think its a big issue so long as the car has good oil and you tke reasonable care of the car
