is a wastegate reliable enough to keep the boost consistantly at 6 pounds by itself or should i get a boost controller?im kinda runnning low on funds

The word "consistantly" does not really fit here. The turbo will be a the 6 pounds only when the gas pedal is floored and the RPM's are up and ... However it will not go over the 6 pounds unless the wastegate were to malfuntion. The BOV is more needed at higher boost however it is nice to have - just in case the wastegate were to malfuntion.
The boost controller goes in the vacuum line on the wastegate. limiting the amount of vacuum that goes to the wastegate. By doing this it allows you to build more boost before the wastegate will open. The WG still opens at the 6 pounds, just that the BC is preventing is from getting the 6 lbs. Kind of like pinching off a hose will still allow flow but at a lesser volume.
Man I think I getting confussed by reading what I wrote!

RE: wastegates?
The wastegate lets the turbo reduce lag while preventing it from spinning too quickly at high RPM's. The wastegate is a valve that allows the exhaust to bypass the turbine blades. The wastegate senses the boost pressure... If the pressure gets too high then teh wastegate bypasses some of the exhaust around the turbine blades, allowing the blades to slow down.
The BOV is exactly how 99civic_boosted explained it... it allows excess pressure to escape saving your wastegate/turbo, its really only a problem with small turbos. it's pretty much for looks and sound on a large turbo.
IMO all turbos should have a BOV... they sound so sweet.
