RE: more horsepower

Big sucker air cleaner and EFI Race Tuner with a competent tuner. For more HP get rid of the pipes.

RE: more horsepower

PCIII is good too, good canned map or custom tune. The high flow air filter (SE A/C or Ness Big sucker, etc.).

RE: more horsepower

Power Commander, no need for the stage 1 then, the power commander will replace the map settings anyway then. You need to open up the intake some more though one way or another. You have the pipes for more exhaust, but you're sort of defeating the purpose by not letting more air in... just a little help.

RE: more horsepower

I have a '06 Heritage with Vance & Hines Big Shots. Put on Stage I and SERT. Much better performance and ran cooler after dyno for race tuner and synthetic oil installed.
