hey i just today got to start my 13b-re.!! its very exciting. im going to be in the market for a good b.o.v. and am curious as to what exactly would happen if i used a bov that wasnt sequential with my stock twin turbos.....sorry if its a dumb question but i wanna be sure of what i do.

Doesn't a sequential BOV relieve pressure with different sets of springs? You should be fine with anyone that you choose if you're running stock turbos...
