    Looking for info on setting speed limiter up on a 2020 GT500

    Wanting to increase speed limiter on 2020 GT500 but seem only allows 186 for vss speed limiter, is this all, or what do I need to change for disabling vss limiter?

    Looks like others are just writing in a higher number than parameter says it uses, setting show 0-186, most people are putting in higher numbers, does this work?

    I am wondering the same for 18+ Mustang GTs as well. Same max calibration limit of 186, but I am seeing people put in bigger numbers with no apparent issues. Not sure if it works though.

    OK, help, anyone. I have chage the speed limiter to 235, it does not allow to exceed 186, as stated in box. Stock 180, modded 186. Anyone help?

    That's interesting, but I guess expected. Wonder if they are working on a patch or OS mod to raise it higher. I am pretty sure 15-17(?) GTs have an OS mod that fixes the issue on those cars.

    I found a 15 mustang GT and the limiter can go up to 496 mph. Sure wish I could get the attention of someone who could change it.
