Welcome to NSR-WORLD.com.
Now dont bring that many BARF'rs with ya
The 030 card is going to change some of the mapping, but I don't think it will do so much that you will need to rejet the bike when the rest of the bike is 100% stock. With no changes to the airbox, intake, or exhaust you should be fine with the stock jetting.
I ran my NSR all over the bay area with stock jetting (with a derestricted MC21) and had no issues. Once I went to a Jha air box, and started messing with the intake/exhaust was when I started getting into the jetting.
Problem with our area is that we can go from a nice warm 85 degree day in San Jose at near sea level, then get up into the hills where it may be 55 foggy as anything and be 3000 feet above sea level. I know when i got into jetting my bike it sucked cause there was never a perfect middle ground (except for the stock setting with stock airbox).
Good luck, and I think you will be happy keeping the NSR instead of selling it like you were thinking.
