i am trying to settle a dispute..someone says you cant get any gains from having adjustable cam gears on stock cams..but i say you CAN get gains after some tuning..TRUE? FALSE?

i have 2000 civic si, if i put on some cam gears like, skunk2 or toda on my stock cams and get it dyno tuned, will i get any gains? if i get some CTR/ITR cams and put some adjustable cam gears on them, will i get gains compared to CTR/ITR cams with stock cam gears?

 

you can gain some power with stock cams
