Sounds like the best option for you is going to be looking at chipping it with the different modes. I know a lot of guys on here really recommend the diablo brand chips. i have one myself and have been impressed with it. Thats what i think you are going to hear a lot of on here. However, im sure there are certian other thinngs you could do with gearing and such as well.
