I have a shim, and vforce 3 r reeds, and will have a power commander for this winter. A small chance a pipe or Dynoport Y pipe. Also doing the ves solenoid delete, and try some pink springs. Would think improved air flow potential into the engine could help. I realize 2-3 hp is virtually un noticable by seat of the pants, but added altogether, every little bit helps. And it might add a sled length in a drag race over a distance.
