| I recently installed Greddy smic's that were used. They are in good condition so I know they haven't caused this problem. I'm only boosting 10 psi instead of the 13-14 that I used to. I've checked all couplers and even did a boost leak test. I can hear air escaping from under the plenum, down where the intake hose for the turbo is connected. I yanked around on it, and tightened the clamps.... all is well. Am I hearing the stock blow off valves or wastegates? When you install larger capacity smic's, do you have to crank your manual boost controller back up to make up for the capacity difference? I deleted the carbon canister while I had the stock smic's out. I followed Robo's tutorial and did everything exactly like he said. All caps are in place to cap off various connection points. Any help would be greatly appreciated!
