OK well I'm looking for what charts or tables to Change and like how much should I change them
Thanks

There are several sequences of videos on Youtube that might be a good intro for you. Calibrated Sucess comes to mind.

I would suggest studying. Anyone can buy software. That doesn't make them a tuner. We were all new at one point. It's not just plug and play. The first trick on learning to tune. Is knowing how a engine works. Make changes on only the tables you understand. Might help out to get a base tune. Then you can modify off that.
