Which 2.0 OVTune to use

I just rec'd my 2.0 Tune Pack from OVTune. Their are LOTS of files/tunes to choose from. I'm running a stock 2021 TRD Off Rd. and want to install the 91 Octane Premium tune. What's the diff between "04C20_Premium_Stock.vft" and "04C20_Premium_Stock_Thx.vft"? Which one should I install?

 

Stock=vftunes 2.0 stock configuration
Reg_stock= regular fuel 87-89 on vftunes 2.0 stock configuration
Premium_stock=premium fuel 91-93 on vftunes 2.0 stock configuration
Premium_stock_THX=premium fuel on vftunes 2.0 stock configuration plus THX(advance throttle configuration)
4.88 or 5.29's are gears
33 or 35's are tire sizes

Which one depends on you...try them them both.

I have the performance 87 2.0 tune and love it. Only have experience with the regular 87 and performance. The regular 87 is good everything is very linear and drives like what it supposed to be stock. The 87 performance has a sensitive throttle and i like it alot more. New Rev limit is 7k

 

Have you tried either of the Premium stock tunes to see how they compare to the Regular stock tunes?

I've tried both Premium stock tunes tland I liked the tune w/o the enhanced throttle response better.

I'm interested to get feedback from folks who've tried both (prem & reg. 2.0) tunes.
