turbo sleeper

i'm trying to build a mean sleeper, turbocharged h22a accord. i don't care if someone hears my turbo WHILE i'm driving cuz by then i would have already (hopefully) pulled ahead. i just don't want them to hear AT the line or when i'm driving up to it. is there anyway to get rid of the "psssst" of the BOV? would turning the boost AAAAALL the way down then turning it back up when i'm on the line work? thanks for replies!

unless you had something that adjusted all of the fuel parameters then no. you have to have preset sort of stages. in which your fuel and everything changes when you change boost

yoru best bet would be to get a bov that isnt very loud...maybe a stock 1g eclipse bov if youre on a budget, i dont think theyre too loud
