Re: 2011 Mazdaspeed 3 | HFS-4 Install
First I thought you have a stock turbo, anyway, you are making very nice numbers.
What gas are you running on? Is that BNR Stage3 turbo you have? If yes, it is exactly the same turbo as I have. And I am in the process of adjusting the HFS4 system right now on my Mazdaspeed6).
