Hey guys,
New to the Skyline scene
i have 2 quick questions for your neo rb25det Gurus
1) I was told that by blocking the little hole on the inside of the stock BOV that it will increase performance and induce a louder spool and release effect.
Is this true or false
2) What does that lttle hole do, im no expert but it looks like some sort of pressure regulator or something,,
Please see attached.
Thanks Gents.
