So... after reading through several threads about HKS RS and BOV, most of the conclusion I get is that if installing those with no tuning (for intake), it will actually be bad for power.

So the input I need is this.. I would like to have intake and BOV because they sounds nice.... maybe loud but stil nice.. However, I do not wish to experience power loss. Any idea what can I do to get the sounds without losing power?

Or maybe it's just not possible to have the best of both worlds.

Please let me know... any input is greatly appreciated.

P.S. the reason for buying these without tuning is that my friend wants to buy me all of these.. including the exhaust...
