PI cams and PI intake dyno results

I was hoping and estimating low 230s hp with the addition of the PI intake and FRPP and came close. Charts are posted below. The results are a gain of 7 max. hp and a loss of 9 max. torque. I am still running stock timing with 87 octane gas, so maybe it's time for a T/A or chip and premium fuel? Previous dyno was done with Steeda Pulleys, PI cams and Bassani catted X.

SAE dyno results. I know it says STD on the charts, but I saw them select SAE on the dyno and was assured it was just the chart label.

Some possible explainations of the tq going down from the guys at Mustang Magic, is that the car is running rich due to the PI intake and compared to last year's temperature was 20 degrees cooler which makes a car run even richer. I'm of the opinion that since the runners of the PI intake are longer than the NPIs that is why tq. went down and hp went up.
I welcome your comments.

thats odd. with my pi intake i felt torque all over the powerband, even around 2K cuz 5th gear pulled harder than before . 2000-4500 i felt a definate sotp difference.

Looking at your sig and comparing mods, I had the PI cams installed prior to the PI intake. With the PI cams, I noticed a SOTP torque increase down low as well as hp up top - and it showed in the previous dyno. When I installed the PI intake, I didn't notice any torque down low being added with the PI intake, just felt the hp up top. Doing it in the reverse order, things might have been different. I have seen some instances where the order of mods make a difference in where the most perceived gains are from i.e. exhaust.
