Hey guys ive read the old threads and a bit of talk with other people on the site and some speedshops but still no one can give me the average sort of boost pressures i can reliably put in to my 2006 2.5l wrx and ideas as well as the pros and cons about manual to electric boost controllers , i want to have a sort of set and forget feature and do i have to have the car retuned to match the extra boost pressure !!
