depends on your setup.

Skunk2 or Spoon Cams are great for mild setup. More agressive would be Toda or Jun if yo want to hassle of the high maintenance. Depends on you, not necessarily for more power but you're also looking for more reliability.

A lot of ppl I know get toda cams for the wrong reasons and they end up selling them b/c they dont know what they are all about.

Toda Cams are strictly for race use, spec b, and c.
