Hey guys i am helping my buddy hes got a 08 f-250 manual and his truck want build past 5 psi boost no matter what. It still drives good exept till you step into her she dont do much she lags around.I dont know anything about these so iam kind off lost. I read that these turbos dont have waist gates just those fins that control the boost, is there a way to test this turbo cause it seems to me as if its just not building boost due to those fins dumping it. Thanks
