got my stage 2 file yesterday and its great!
sal informed me that this is completely new and modifies the VANOS for power increase so there is no way that it will knock under full load
definitely better than the ones theyve had in the past. it feels 100% like stock and im really glad im running it. good stuff guys
oh, and power increase feels pretty nice too. my butt dyno is enjoying it.
