Seems to me those are pretty respectable gains seeing as how it hasn't been tuned yet.
Darn near 10% gain in HP.
I myself am seriously considering getting the FI CBE/HFC combo with 18" res, even the youtube recorded sound at WOT make me all
inside. My only concern is about highway drone. Any of you guys that have this or a similar setup installed have an opinion? If this has been addressed previously in this thread, the thousands of replies have intimidated me beyond attempting to find it lol.
Nice job there Captain
