Aim for low-mid 11's first, then pull fuel from there and see what she likes.


Wow, seems pretty lean, what kind of boost & timing are you running & on what turbo?

I run 94, think I have an M12 nozzle in there, 50/50, with their older pump (probably their first gen, not sure if its 100 or 150 psi, have had one of their new 250psi pumps sitting on the shelf for years....). If I go much leaner then 10.5:1, I start to knock (~10.5 at peak cylinder pressure & lean out to ~11:1 as the rpms increase), boost ~30psi.

Haven't played with these Link settings for some time, have they changed options for how meth is controlled? Thought mine was setup so when the set point is triggered , it enables the secondary fuel map (& not actually altering the global)?
