If I boost my power output on my 2023 supra 3 L automatic either by tuning or by aftermarket parts, how likely am I to negatively affect my warranty? Thanks in advance for any thoughts

I naively asked the same question of a few other Supra drivers at the meetup yesterday. One fellow said he voided his warranty within a week of getting the new vehicle, lol. The mods to his engine were amazing and that's just what I was able to see.

The sense I got was that there are very few things you can do to the engine or powertrain and keep your warranty intact. A guess a JB4, or anything you can remove without a trace, would probably be ok.

I'm envious of anyone who can just ignore warranties.

Even though I was kind of hesitant to ask, now I am very glad that I did! Just to hear all the cool comments! What prompted the question was that I had seen posts in the past that mentioned that possibility. So I kind of knew already. But I am indeed glad that I asked.??

You never had your warranty
That's because I know Hector is going to be running three Honda Civics with Spoon engines, T66 turbos with NOS, and a MoTec System exhaust. You know I can't lose...
