The fuel system. Have replaced everything from the in tank fuel module to the injectors. Injection pump is flowing 300cc's of fuel compared to the stock 170ish. Has brand new lift pump from cummins. Very healthy motor. Timing is bumped up to 16 degrees. Has #6 plate and 3000gsk. Injectors are brand new 370's with the auto spray pattern. Its no means built as in "ready to dominate the sled" but its been built right and to still be daily driver material.
