WTF can you do to adjust the boost on a internal wastegate turbo?
can you take off the inernal wastegate and put on and external one? can you buy somethin to adjsut the pressuer? if so, will it be fully adjustable?....ect...ect...

 

I've never used an internal gate, But you do have to modify your turbo to make it external. I'm sure someone can help you with you question........

 

maybe an external boost controller?

 

If you want to run more boost than the stock spring, just run a simple manual boost controller. http://www.boostcontroller.com

If you want to run less boost than stock, then you've got other issues to deal with.
