I must be the only unhappy customer. I wanted the stage 3, let the owner of FF talk me into the stage 2. I put it in my 69 Sat with completley rebuilt suspension with 11/16 tie rods. I put the Hemi in and when I took it for a ride, it is one finger, typically Chrysler, overboosted power steering. They told me it would be similar in feel to my buddies 06 GTO. Not even close, feels just like stock. I am going to look into the pressure reduction mod for the pump, but FF led me to believe there would be a significant upgrade in the box alone. I should have followed advice on this forum and insisted on the stage 3. Other than that, they do nice work, but I am not going to all the trouble to lift the engine to pull the box. My advice would be to go with the stage 3.
