I have a 07 mustang gt, 4.6l with a HO procharger blower kit, just had it dyno'd and tuned it to the max, pushes 10lbs of boost, changed the gear box, and installed long tube headers... besides adding a pully, I have been told that it will blow the engine if I add anything else, and that I need/should change the pistons and piston heads, or get a bigger engine. I just want a second opinion or tips to push a lil more hp, and possibly run mid 10's.
