The H/O cams that KRC and AirRam sell are different or the same as the cams in the H/O Dakota? Was never sure (Sorry if its been posted)

I hear the typical gains are 25-30 at the wheels....yay or nay?

Also that they do not require a tune even though it would be a great help.

Does it make the truck sound different? (personal question lol)

 

they are the same cams straight from dodge. as far as gains maybe a good 20 but not more. the superchips tuner will be a very good addition to the h.o. cams
