yep. since you are dumping to atmos, the gas can escape quicker which will help the turbo stay within your limit(set by the bcs or a controller). it also helps you spool quicker. dont know how, but many have said it does. i have been on tuners when looking for info on the atmos dump. everyone there liked it, cept some didnt like the noise. what brand is that one in the pic?
