Not sure on Kracka's car, but I personally wouldn't do this on a stock turbo car.

On an FP/CBRD turbo car it would probably be worth it.

Also, its really the last mods you can do on some cars before more power can only come from a bigger turbo.

edit: but the link I showed above, the guy showed 20whp/20wtq on average from the MAP rev 2 and a big ass teflon spacer.

I think 20whp for the bulk of the powerband on an aftermarket, stock-frame turbo would be what I would hope for, but WITH the TB, not just the IM (that makes no sense to me).

On a stock turbo car, peak power may not be affected much but I'd bet that the powerband would be improved similar to this test that was published a few weeks ago:
