So I just got my 21’ Supra unlocked with a custom MHD tune. I am gonna enjoy it for a bit and possibly do a flex fuel upgrade as well. Depends, this is just a daily driver I’m not tracking this car at all, just loving it for what it is. But I’ve heard the xHP transmission tune is a good tune to really make the transmission come alive, especially if with a tune with flexfuel. Anyone with first hand experience or knowledge think it’s “worth” it? I know that’s subjective, but if it makes the car perform better while being a worth while purchase I’m all about it.

Took my 2021 Supra and got it unlocked and custom tuned for 91 octane. Went from 390 WHP to 460 WHP and 421 lb-ft torque to 563 lb-ft torque! Was told if I want more power(500+) to go E85, but I’m just not sure I need all that for a daily driver haha. The drive home was definitely a bit quicker.
