Wow this and others interesting results....but I wonder if they would pick up much faster spool with a bigger dp/exhaust.

We had a customer come to tune with a D15B7, hf manifold a 50 trim T3, and a 2.5" DP. He made 141 on our MUSTANG dyno on 7 lbs. We fabbed up a 3" DP for his car a month later, put it back on the dyno and with in 3 pulls the car made 176 on the same boost... It now blows the tires off in 2nd 
This is with a D15b7 so think of what you guys with the bigger engines will gain...
