VF Tune Question

I just received my tune pack from VF Tuner. I'm looking at the list of tunes to choose from and I can see "premium/reg" is for fuel type, "33/35/stock" is for tire size,
"488/529" is for a re-gear, but what about "thx" ?

I have a 2021 Tacoma TRD Off Road V6 with stock tire size. I don't know whether to go with 04C21_Reg_Stock.vfc or
04C21_Reg_Stock_Thx.vfc

Thanks!

 

I believe the Thx is a more aggressive throttle response.

 

Wow, a more aggressive throttle response!? I'm just getting used to how much better the shifting is, and how much easier it gets up to speed. I'm going to wait a couple of weeks and then go with the "Thx".
Thanks TacoManOne!
