Hitting top speed limiter at 155 in 2012 Camaro SS. How do I get rid of it

[JASON11WS6]

Hitting top speed limiter at 155 in 2012 Camaro SS (on the dyno). How do I get rid of it? Car has a large cam and needs to get past 7k but its getting stuck around 6k with this limiter.

I went under speedo and the limiter there seems fine. Nothing says 155 at all. Couldn't find anything under systems either.

Thanks
