Hey guys, We have a 2001 35' motion xp with stock 500efi's on stellings standoff boxes running bravo xz drives. 34'' bravo one props by B-blades. Boat runs really well as is but we are looking for a little more. Toying with Whipple or Procharger but we are trying to keep the outdrives alive. Wanting to know more about these kits because it seems to make the power we are looking for. Would like to know the exact dollar amount these are going for. What comes in the kit and what do we need to do with the ECU's or other components before these will work. Thanks so much. Shaun.
