6882 Oh i didnt purchase it I saw it on a fb JDM parts group I think it was like $500 which is way too much for someone to take and modify lol.6880 [MENTION=2822]Doppelganger[/MENTION] How much was it?!
6886 - The Synapse valve is great. I have one and love it. But the OEM valve is more than capable. If you aren't sure or it starts leaking boost, you can always crush the plenum a little bit with a block of wood and a rubber mallet. I laugh, but I'm serious. My factory valve is crushed a little bit.6883 do you guys think my stock bypass valve on my 05 sti should hold the FP green boost levels or should I get a synapse synchronic?
I only ask since I don't want to waste money on a blow off valve but I've heard good things about this individual valve and have heard that stock bypass valve fail at high boost

6887 did you see any benefits while using this valve. I'm skeptical of their claims and would only replace the stock valve if necessary and have chosen to go with the synapse if it's necessary.6886 - The Synapse valve is great. I have one and love it.

6889 Makes complete sense and is why I've been eyeballing this bypass valve.6888 - The only thing I didn't care for about the OEM valve was the way it would dump all the boost in my intercooler system before closing and allowing boost to build back up again. It's not easy to describe. Basically, I used to drive some really twisty roads where I'd be WOT, then half throttle and WOT again. When going from WOT to half throttle, the OEM valve seemed to dump everything. The Synapse valve seems to only dump boost until pressure is equalized at half throttle. So when I'd get go WOT again, the OEM valve's complete dumping of boost would extend spool up to peak boost time where the Synapse valve seems to get me back to peak faster.
I hope that makes sense.
