Id say gears, Im sitting same spot as you, finishing up the full exhaust, and got tune + CAI. I really dont want to mess with the intake any more or pullys because Im looking at a supercharger down the line. And from what Ive read, need stock stuff on there or the kits come with new parts. So Gears, thats my plan, Like 2 months its trany fluid and read end change, was going to put my gears in while doing the changes. Just something to think about.
im being the oddball and voting tb/plenum because you've already got a cai and full exhaust.. a tb and plenum would help.. if your car breathes better it will make more power, that's simple. if you areplanning on f/i i say wait on the gears till you have a 31 spline build.. that's what im having to make myself do every time i see a thread on gears lol
