    Mine is a VAC MLS .140". Lowers compression to around 8.9-9.1.

    Do you mean to boost beyond 10 psi on a setup?

    Great thread as I was just about to start one similar.

    What do you guys think about the Cometic MLS headgasket that comes with the Technique Tuning Stage 2 turbo kit? How reliable is that or would you guys recommend something else?

    VAC Cometic MLS is what most people are using even though I have seem a few fail. It all depends on your install procedure.

    I would like to know the answer to the above also?

    If your M3 doesn’t have 3 pedals and 2 doors, I would really consider contacting BMW to confirm the authenticity of your incorrectly badged mid-sized family sedan.
