The 58t is what am running if u want a lol more low end then a 56 or u can get ur 54 but higher u go from 58 the more u get to the top end my friend runs spur gear don't know what size it is but he has more power at the wheels than me on the stock 58

This is backwards. The more teeth on the spur the more torque and bottom end power you will have but less top speed. Vice versa for less teeth on the spur. The 3.3 can carry pretty high rpm, but suffers in bottom end torque, therefore I would stick with a higher ratio, like the 58 tooth.
