This is my first turbo car and i understand the basics i just have some questions. All i have installed is a HKS BOV and a COBB intake and the car is a blast right now but i am always looking for more. I am intrigued about boost controllers. Would this be a safe next mod? How do they work and how much boost is stock car running? So what is a reasonably safe ammount of boost that you can run without fuel upgrades? I am going to do some TRK plugs, which ones do you guys prefer? I am new to the 4 cylinder cars, used to V8's but i love to learn so anything else that might seem pertinent is always appreciated. ---08BLK
