Want to get a tunner with auto tune and put some cams in. Bike has V and H big radius pipes 2into2 SE heavy breather factory download. What would be the best bolt in cams to install. What have others done what kind of results to expect.

 

Not enough info in your post. How do you ride? What are you expecting out the cam? High TQ? High HP? DO research. Narrow your choices. Then post and ask how one cam compares to another if you are still undecided.
