what is the best gearing set up for more top end

[apex4]

Hi what is the best set up (gearing with orginial chain) for more top end on a 08 apex ltx gt completely stock with 162 trail studs and 1.25 track. I would like to get rid of some bottom end anyway as the sled has a huge amount of torque.

24 is the best for shortys, 23 is the best for long tracks.

I run with 24 and I love this!
Helix at 6-1!
Drill 3 holes (1 1/4) in the base of the air filter box.
I can play with Apex with 25th gear on acceleration
