I basically just wanted to see how much people out there are running high boost like 12psi or more on there lt1 engine - who just changed the pistons and rods over to forged. Eveything else stock. Basically I'm thinking about going that route. It's allot cheaper. I want to make 550-600rwhp and torque around the same power. Anyone have problems with there set-up - and how much power are you making - Mike
