I would agree. The 5r55s robs us of allot of power. I had my car tuned at the same place on the same dyno twice. The first time I was using the stock 5r55s and converter. the second time the only changes were delete plates, a built 4r70w w/ a pi converter and a 76mm turbo vs the 70mm that was on it the first time. The car made 150rwhp more at the same boost level!!!! Hell I even had big drag radials on it the second go vs hard low profile 20's the first time.
Come on man. You know that is not apples to apples either....not even close. I mean I respect Joe at Dynospeed and all but really ?

. No but in all seriousness, that original post by BBR was missing something. Something doesn't sound right to me. If i am wrong then i'm wrong and i'll admit it but i honestly don't believe it.
