boost help

ok heres the deal, i bought the 2,0 wrx with a home depot mbc, took that off and ran a perrin ebc as a stock 1 but in fast mode...
boosted to like 23.4 lbs, noot cool so i got the small brass restrictor put that in and ran the lines like stock with the tee between the turbo and wastegate.... now im running wastegate boost of 9lbs no more i have the perrin in slow mode like the factory ebc from subaru, what could i have done wrong... its not making sense the perrin website says i can run the ebc in place of the stock 1 with no retune i have no clue what to do next i reset the comp. still running on wastegate i needs some help here lol any would be great thanks guys....
