03 Xterra S/C.....What is a VG33DE?

I just bought a 2003 Xterra SE with the supercharged engine. From everything I've read, there is a VG33E and a VG33ER engine for the Xterra in 2003. My VIN sticker says my engine is a VG33DE. I can't find ANYTHING on the VG33DE. Is it a misprint from the Nissan factory? If so, that's not cool because it is on a VIN sticker! The only thing I found on Google is this...https://www.zdriver.com/forums/300zx-z32-performance-technical-47/vg33de-build-19254/

But I can't find out anything on Google or Wikipedia on what a VG33DE is. Can other Xterra owners with 03 models that have a supercharger check their sticker and see what is says? Thanks.

You're overthinking it. My 2001 X was labeled the same way

@Prime Mentioned this as well. If you have a VG33E, then it should say that. I have a VG33ER and mine should say that. If everyone's VIN tags say VG33DE, why is there no information on this on Google or Wikipedia. You have a 5N1E so from what I've been told, that means you have a non-supercharged engine. I have a 5N1M which means I have a supercharged engine. So why are our engine codes the same? Yours should be VG33E and mine should be VG33ER. Seems pretty simple....???
