Final update:

Got everything tuned by Phil of Element Tuning a couple of weeks ago. Video can be seen here:

I also discovered a mistake I made when I re-routed the brake booster line. This could have been a huge mistake on my part with reguards to safety. There is a check valve that is pressed into the stock brake booster line that keeps the boost pressure from going into the assist system.

This is a critical piece to install back into your brake booster line.

I had left it out because it is pressed into the stock vacuum line and is very easy to overlook. Well when this valve is not installed, the boost pressure can act against the brake pedal and cause a huge resistance AGAINST your foot. Basically if you are on boost and ripping into the car and have to hit the brakes, you first must push all of the pressurized air out of the intake manifold before you get any brakes. Very dangerous and I almost slammed into the back of a car because of this.
