I just got a cai and tune from breenspeed, and I can't make up my mind what should be my next mod. I'm thinking about 4.10's but my car came with 3.55's and I'm not sure if I want to change gear's or go ahead and get the zex kit next. What do yau'll think ? Also, how much time should I pick up in the 1/4 (if any) with the gear swap ? Car is a manual with 93 oct tune. best time so far was a 13.5 at 105 on stock tire's.
