You're asking a much more general question than you think...
It has nothing to do with a VR6, 12V or whatever; if you know how cam timing affects hp, torque, knock resistance, VE, etc. then you'd already know the answer
Well no i think you basically answered me. It went down like this at the shop I'm working at as a contractor, "hey this guy wants cams and such and such tuning company had a tune they said makes a big difference with these cams.
And my response was, " Yeah well they sell cams and shit so thst doesn't surprise me, however, they don't have access to anything in the tune I don't have access to, it's just a matter of me being able to push fueling and ignition timing more, so there's nothing in thst tune that we can't do with the Kess v2 setup and ecm titanium and pro tuner and stuff.
And him pushing further so I said look I'll ask on nefmoto, but the end result is the car doesn't have variable cam timing so in reality there's nothing magical about their tune.
