I just put in a baileys diverter valve and when i start up my car and drive for about 10 minutes everything is fine then out of no were my car runs like ****. when i floor it it boosts up to like 3.5 and then it kicks in and ints fine when it is around 3 i cant hear my intake like i should what can this be it ran fine before the dv.

 

check the vac line, it may of came free or the valve connectionsare nottight.
