I got my FD through MOT new plugs helped . As I was briving up the road I started to lose boost. When I got home my 11 year old HKS bov was blowing out front on boost so I replaced. Now I have more boost but not the same as before would any one have an Idea if the over boost popped a hose or where to look.
Its a twin pack running as a single with a gready boost control power fc and commander.

Help if you can
Thanks
Mike

 

Sounds like a vaccuum leak. Best bet is to use a fogger to check for vaccuum leaks.
