If you are looking for tune files you won't find any. There are a few bits of information floating around the internet on tuning tips that may help. From what I have found most of the Nissan/Infiniti crowd have their cars tuned and don't have the tune files unlike the LSx people that have a much larger DIY crowd that self tune and share information. I would guess it's because there is a larger base of people into the GM stuff.

Truth. OP seymore4 is our resident Uprev guru and he'll hook you up if you're looking for a tune. He's also very active on this forum and knows how to take care of his customers, his customer service is unparalleled. BTW Uprev is the company that created the tune, Osiris is the actual tune.
