ok i posted about fluttering blow off while back and got a hudge reply out of it...now im finally runing turbo and now that i know its bad mine is doing it...go figure....
it mostly does it at low boost and spool and im runnig a greddy type s on a t25

Do i need to tighten the spring or lossen it?

second...im surging in the very end of my second gear and mid third at full open throttle....if my blow off spring isnt to the right tension as obviously its not could it be releasing boost and causing this or do i need to look into something else as the problem....
