Yes, it will hurt overall performance. Unless you got bigger air moving in and out, its not needed.

The upper intake plenum works better with a 75mm TB. Thats what i have on mine a 75mm TB,C&L upper intake plenum, and a 85mm C&L mass air meter and my car runs just fine ive been able to run a 13.4 at the track
