I have been trying to find out the differences between the 3UR-FE US LC 200 381HP version and the versions sold to the rest of the world which produce 362hp.
When checking the engine parts list for a gulf spec 5.7 and a US spec 5.7 i noticed they were almost the same with one difference, the Gulf Spec didn't have a Manifold Air Injection System listed under the engine parts section while the US 200 did.
I'm not a mechanic, so i do not have much knowledge regarding this topic but would this be the reason why the American versions produce slightly more horsepower and torque?
