If you are going to start tinkering with your boost levels this is what you need to do:
Purchase the following:
An accurate boost gauge.
Electronic boost controller
Fuel Pressure regulator
Air Fuel Ratio gauge
Wide band O2 sensor
Have these parts PROFESSIONALLY installed and pay the money to get it tuned.
If you just get a boost controller put on and give it a crank your fuel will lean out and your engine will detonate.
Also it might not be a bad idea to get a fuel controller from Apexi. That will cost you though. So will the O2 sensor. You can get away without one, but you should just leave the boost alone after its tuned.
