Looking for mph to be increase in the program from 186 to 235. 2015-2017 mustang uses 496 as top speed so I am sure it can be changed.

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.

eric@hptuners looking for help?

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?

Will have on Dyno tomorrow, I can report back, seems no answers? High speed event next week, wanted to remove on 2 GT500's.

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?

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?
