I have the PCV and AutoTune, I just started with a map that seemed closest to my set-up then had to go back and balance the map after every couple rides. I highly suggest getting the AutoTune because it will dynamically adjust your map for you.
Still learning about the PCV with autotune. I have both, but the powercommander website doesn't have my current mods (FCI w/out box and full yoshi exhaust). It will probably be awhile before I get to a dyno for a custom map. I'm assuming that the autotune will just keep me close to my map settings at all times. If anyone has a map for my mods please send!! [email protected] thanks!!!
