Whatsup everyone! As the topic says, my evo's rpm has been dropped after i change to an aftermarket BOV. Questions are 1. Is this an normal problem for changing BOV? 2. Can i fix this by refreshing my ECU?
Thanks for looking and i appreiate the opinion!!

 

you need to search but I'm in a good mood

if the valve is VTA then that is your issue

you could "band-aid" this issue with an ecu reflash however disconnecting your battery won't do much good

do yourself a favor...if you are running a stock or stocklike turbo get yours an evo ix diverter valve
