Default Lack of performance, Help!

First off, bear with me I have never posted before and I'm new to the 5.0 Mustang scene.

I need some help figuring out my combination. I just refreshed my 5.0 with new rings,bearings etc.. The heads are ported E7's, e cam, Explorer upper/lower intake,4 pinicle(?) 19lb injectors, 70mm Maf from a 94 stang, 65mm Explorer TB, JBA 1 5/8" unequal length, catted BBK 2.5" H pipe to Magnaflows with dumps. The rear end has stock 3.08 gears (sorry, car is a 91 GT).

The car runs good but just really seems to lack any power. Is there something in my combination that is totally wrong or that I need to change? Please help!

I believe so. I used the post off of this site to set it but I'm still not sure what would be the best timing to run with this combination. I have it set at 13 if I remember correctly.
