I purchased the Mrev2 when it was introduced and I have a 2004 G35 Sedan 6mt with stillen gen 1 exhaust system and injen cai. I wanted to know if anyone knows if my car maybe running lean on this set up with the New mrev2 added.

 

from what I have read there is a slight chance this could occur. If you hear knocking or have serious concern you might want to dyno just to be on the safe side. I would consider is 75 dollar diag fee that could prevent a major problem.or
