What do you think a build of this type might come in at?

Anyone changed the cam timing on a mostly stock but w exhaust turbo and seen any mid-range improvement?

Thanks for your opinion (s) in advance.
The air pump is proven on a thread somewhere to enhance off boost response because it actually runs air through the turbo at lower speeds. That is all it does anyway, pump air into your exhaust. I might be tempted not to yank it without a lot of consideration.
