So I have a 4" TurboXS bellmouth DP, 3" exhaust from there back, Cobb SRI, and I have an OS tune from a local guy scheduled for august 8th. I plan to have a gauge cluster installed by then: AFR, boost, and oil pressure. I'm also wanting to install an MBC to turn the boost up. My 06 WRX feels slow as hell haha. What kind of boost is recommended for my stock turbo that will be quicker, more efficient, yet still not too bad for the car. Also what kind of power am I expecting from these mods?
