It was originally sold at Passport BMW in Maryland.
So it looks like an N52. I did a quick Google to try and find the difference between LEV, ULEV, SULEV. I found the standard gov definitions. But I also found a post stating the difference in the N52 LEV and ULEV is supposedly emission catalytic converters.
Anyone know if this presents an issue for software tune when adding headers and/or 3-stage manifold?
