My 2005 Chevrlet 2500D 4X4 crew cab makes 605hp/1092ftlb tq with this turbo, efi live and other modifications. No internal modifications to the engine. The truck runs mid 13's all day long and pulls the occassional sled. Turbo has been in truck for a year now with no issues. Highly recommend this turbo.
