Yes, you can run them at o. you will run slightly leaner but with the stage2 injectors you will be fine. stage2 makes you run pig rich.red05srt said:is anyone running these cams with no fuel controller? a guy at a performance shop told be i would blow my motor because of the added air... it sounds kinda scetchy. i figured i would get some of yalls opinions. my mods are s2 with out toys, tbe, intake, charge pipes, bfmic and thats about it on the performance side of things. im going to run the bc stg 2 cams with the cam gears set at 0 until i get on a dyno. i have the afc neo but im waiting for my tach adapter to get here and i want to do the cams tomorrow. your opinions are apreciated.
