I am running 10+ psi boost on my 07GT. Its about maxed on the stock internals. When the new 5.0 came out 5-6 psi kits where available. Then SC manufacturers advertised 8psi kits. Now it appears people are running 10psi boost on the new 5.0. How is this possible given the 5.0 has 11.1 compression and sintered metal rods?
