Make sure you do have a flash ready for the 3.73 or you will go into limp mode as soon as you hit 4th gear..
If you're shifting at 6400 with stock height sidewalls 22" wheels will get you to 112 20" wheels will get you to 105 19" wheels will get you to 101 18" wheels will get you to 98 17" wheels will get you to 94 Since those gears should get you to those speeds in a shorter distance I think you're going to be trapping in 4th.
