bro, usually running a external wastgate not only will prevent the boost creep, but turbo will spool faster and it will hit full boost faster than with internal.
Besides, at first i went with external because of the fitting issues, and then later on I learned a great deal about actual wastgate purpose.
I say get a tial 35mm - this wastgate kicks ass, I used to have delatgate mark II before (-aka deltacreep) and let me tell u. It is a big difference as far as reaching full boost at lower rpm, and quicker response, much less turbo lag and no boost creep of course.
Of course it looks better too.
Sounds awesome if u dump it to the atmosphere when running a dump tube like i am.
I say $250 is really good investment for your turbo setup.
Besides that , which internal wastgate will hold low boost appl, such as 4psi for example?
