you still need to buy a pcm from ottp or get a dyno tune at a local shop before you put in the injectors. if u put the injectors before the tune. ehh not so smart

Nope , exact opposite , lower the leaner ...higher richer . I would say your safe at 5K feet to run a 3.1 , that might put you at stock boost level's that high up (12.5). Just watch it if you take a trip to lower alt's or sea level.
