my other question is this a useful mode to use on a stock turbo. u make it sound like it is since its able to hold boost better. im wondering if anyone else whos done this or any tuners can give a lil info
Here are some links on videos you can download and hope you enjoy because I sure did and my dyno numbers speak for themselves.
Update on my numbers:

on a bigger turbo they sound sweeeeet!!
One question though.
An internal wastegate dumps excess boost into the downpipe? and an external wastegate dumps excess boost into the atmosphere?
Is that how they are?

You also gain spoolup and a little topend from dumping.
I have my kit externally dumped and I love it. Yes it is very loud, but only when you want it to be. Under full throttle when the wastegate is wide open it sounds like you have no exhaust.
external....turbo spools fast....and its ****in loud...if u want to be noticed then do it...i dont want attention them keep it goin though the exhaust...my friend could hear my car half mile away....so cops will here you too....and id imagine it would be louder on evo cause u pishng like 22psi.
i got some video of my car w/ my frined $2000 video camera....lot better sound....should get something up early next week of it.
ohyeah forgot to post....heres a pic of my wastegate http://www.enilson.com/evom/AndrewTu...r/IMG_0143.JPG

Tial, Turbosmart, HKS, Greddy
Buy the one you like but the work on the installation of the external wastegate has to be custom. I know Turbotrix now has a machine shop and also they are awesome at welding, give them a call. I chose the Tial 44mm just because of the Vband
