It is stock. It's rather hard to tune as for some reason the top needle is a lot more sensitive. I was told that the top needle is more blunt so it's more sensitive but I went on Nova's web site and it shows the same part as the 321P.
Performance wise, I think acceleration especially mid range is surperior than the JP. Top end is also a little faster but that could be just tuning.
