I would go with the 1.15 you'll have less backpressure issues down the road.

THIS^^^

I would not go T4 .96ar if I had a larger option on any motor over 300ci. The .96ar flows pretty good on a 4.6L ford. My 5.3L has instant spool with a 1.10ar T6 BW 475 with a 83mm turbine wheel. If I had a 6.0L I would have gotten the 1.32ar with the 96mm turbine wheel.
