I ran mine with a 3.25 which is 12psi (with a tune) and i was over 540whp (with crappy gas). Livernois said i was at the edge for stock internals (pistons). My engine failed, i believe the stock oil pump failed but will know more soon. The rods, cylinders, crank and pistons appear to be in good shape, boost away just be prepared to pay.
