engine specs
 

I'm trying to find engine specs for my 2000 jetta vr6. All I know is that it's 2.8L, V6, I'm guessing it's 12v, and it's GLS cause has leather interior and heated seats. I just wanna know what exactly I have, I'm trying to research it through internet and eruotuner, but only little help given there. I've just about figured out what I'm putting under the hood, but if there's something out there that will give it a significant HP gain, please let me know..thanx..
