Brura22 has, I did not. I am on crap 91 octane so I won't be making huge gains anyways. He has said it makes a huge difference. I was looking for more oomph and want to be around the 250-270hp range as this is my daily and I want to keep it until the apocalypse lol. Bruras write up is good too unser the MRX turbo thread. I think its around the 150 page range (I did months of reading before pulling the trigger).
Oh yeah I saw his, as I have definitely read through that thread twice now. I remember him saying something like..... HOLY CRAP, but never really saw any data of it before he disappeared. I am only running 91 right now as well but I am going to try to move into a higher octane tune with Boostane if Randy is feeling generous. If so I can get a 95 octane tune for track days or when I feel like I need the fun.
