i am running 7 pounds of boost on low and 10 pounds on high. and my si has had no trouble. its just the Greddy piggy back system is pritty much crap which only lets you tune air/fuel pritty much. my 2007 civic si sedan is making 267.4 hp to the wheels. just waiting for new computer to come out so we can control vtec and angle of the cams. but anything past 11 pounds on a civic i think is almost overkill for stock internals. but when that new computer comes out then i will get new internals.
