Hey guys. Ok, I've got a couple of general questions about bleeder valves, blow off valves, funny turbo noises, and decreasing boost at high rpm. First, what's a bleeder valve? What does it do? Why would I want one? Second, what advantage does a blow off valve give you? Does it make you spool faster? Third, my turbo makes a weird humming in first gear as it spools, not always, just sometimes. The boost also drops at the top of first and second, down to about 8 or 9. Is that normal? How can I fix it? One more question, what's a turbo timer, what does it do? Sorry for all the questions, I'm just curious! Thanks.
