I just started playing this game recently and I had the same issue, I got all the way to the end and was 2k shy of the Cheever on Golden Bullets. I went back again and made sure to stay at Rat Boy until enemies stopped spawning and also to chain styles, usually by jumping into a slide. By the time I got to the Ice Factory arena I had all available upgrades except bullet damage and I started that arena with 3,600 style points and ended it with over 10k. You nearly double style points by chaining styles.
As of 4/28/14 my Borderlands 2 trading post is officially closed. I am no longer boosting, trading, farming, etc on the Xbox360. I am entirely on the Xbox One now. If you want to play Xbox One with me, send a friend request with a message
to GT zI Drucifer Iz (those are capital I's).
