Does the gauge read a + value when you're driving ?
Get a little 12v wire tester in the motor factors, will save you alot of hassle. You have put your positive battery wire into a "lights" wire.

So it didnt go that smoothly at all ha ha.

As for your readings, i'd say you have it plumbed on the boost side instead of intake side. What line did you tee into?
