Peak boost on stock mazdaspeed6.

[sleeperms6]

Just put my boost gauge on And I was wondering how much boost should I be at with just a Cobb intake? Is it 15psi?

Yeah 15 is the correct number 15.6 to be exact but 15 is about right, shouldn't be going higher than that though.

anything between 15 and 16 is good depending on temperature and other factors. But thats a good number.

how do you make morwe boost on a stock ms6? is it just a tune?

 

[Kiseliok]

tune or MBC

stay away from a mbc. the small turbo and quick spool characteristics can create massive boost at a low rpm. this has been proven to cause blown motors in this motor. if your not careful or without a built motor you will regret it.
