-- Posted by redhotchilis64 at 5:12 pm on Dec. 17, 2008 My buddy is having trouble with his Supra. I drove it a few minutes ago, and it sounds like it's having some minor compressor surges (boost at 10 PSI), but the blow off valve still releases the pressure. It's almost as if the BOV is late, could it be an ECU problem? Maybe a wrongly connected BOV? I know the BOV can handle 10 PSI of boost release, he ran it at 21 before he blew the last engine. -- Posted by johndoe240 at 5:14 pm on Dec. 17, 2008 i would take your question to a car forum or attemt to google the problem -- Posted by IMPALA at 7:58 pm on Dec. 17, 2008 Quote: from johndoe240 at 5:14 pm on Dec. 17, 2008 i would take your question to a car forum or attemt to google the problem This is a car forum, dipshit. OP.. IT might help if your friend stops being a ricer -- Posted by Neodymie at 7:24 pm on Dec. 18, 2008 What kind of blow off valve is it? There should be an adjustment screw on top of it. Play with it. -- Posted by Neodymie at 7:27 pm on Dec. 18, 2008 also it's not your ecu. BOV's are vacuum controlled.
