exactly, even FIs HFCs only made an extra 5 hp with their CBE already on. Im sure if they had done a dyno with only HFCs it would have gained more. And if they had done dyno of their CBE with HFCs already on they probably wouldnt have the gains that they did with it alone. But I do agree the tune will bring the mods into alignment more and gains some gains.
