Does anyone have published / documented power gains when going to the turbo xs fmic from stock?

I have searched, but came up with a lot of"it's fits really good", but no power gain info.

Thanks

 

I don't know of anyone with like a before and after if thats what you are looking for, I know a bunch of people tuned for them though

 

im interested

 

Thanks Ultimate CC

 

My buddy has it on his evo and its a very nice piece for the price, pretty much any of the top brands (ams, buschur, nisei, turboxs, perrin) are all good and get the job done. You just have to look into the little things such as which keep stock bumper beam, which require trimming, etc

 

Good call, I haven't seen anything in this area either. I am curious now as well, thanks.
