i have the scm61 bolted up running w/g boost which is about 14.7-15.6lbs.....im told those turbo doesn't start really pulling really hard till 20psi +....i have everything needed to run 24lbs +...some of my major mods are...272's 1mm os valves, jm fab smim, fully built head, fmic, unorthdox pulleys,fidanza flywheel, and alot of other stuff.....can someone compare w/g boost and 24 pounds of boost on pump (my keydriver chip has a fuel map in it to allow more boost on pump gas)...scm61 users wanted to let me know the real deal...but other experiences with big turbos is welcome as well..thanks guys
