i just instaled the greddy type s bov on my evo 8. im set up at 26 psi with 272 hks,intake,straight pipe.tuned 330whp, should i go single spring mod ? because if i let of at about 10 pounds or lower i hear the turbo backspining or as yall like to call it flutter. but if i hit it hard at 25 -26 she sounds nice.. i think im keeping it like that but i just dont want to damage my turbo what you guys think.. just a quick noob question i guess

 

I did it when I had it in there. Stiff spring

 

so u say single spring ? reason im asking is because some people that have bit of high boost leak ..

 

25 psi you should be fine.
