Default Emission Test Failed - HC high at Idle

Hey all,

I have a Stg 2 setup on my 2003 WRX with Ecutek and 1 cat. All test passed accept the HC test at idle. (Reading 175, limit 150).

Any ideas what I should do to pass?

A) drive it at high revs for awhile on the highway to help burn off the carbon
B) put another cat back in
