Yea the GFB works just fine even in higher boost applications as there are plenty of members running high 20's on their x37's with the GFB DV. I have no idea about the long term reliability of it though. People say its plastic so it should be replaced, but that could be just talk to help sell aftermarket replacements. My guess is that [MENTION=4233]44sg44[/MENTION] doesn't particularly care about stock look if hes swapping out the turbo. However if price is an issue, the GFB DV is likely your best bet.
