hks ssqv and the greddy typeS sound nice

[THEONE]

i had a hks ssq and loved it,the problem is that type of b.o.v vents into the atmosphere im looking for something that will have that hks sound but none of the problems related to removing the return line,like stalling,bucking,stumbling,running rich inbetween shifts and so on.
