Hey I have a 98 ITR motor and it came with toda cam gears on the stock cam, i was wondering if it would make a difference if I were to tune them abit or should I just leave them the way they are which is not touched at all

 

You can usually get a few more HP out of stock cams with cam gear tuning. If you got the cash and don't plan on upgrading your stock cams, go get it tuned and make use of those adj. cam gears.
