Re: vtec single cam turbo,,help
 

look for a vacuum leak somewhere

Re: vtec single cam turbo,,help
 

vacuum leak would most likely cause higher boost bit it would show low on the guage.
i would check all charge piping, and exhaust leaks.

disconect the line to the wg and watch you boost spike up if no then theres your problem

bad turbo
bad piping (leak)

some where in there
