2007 E550 topped at 130mph???
Renntech and other ECU upgrades remove the limiter as mentioned above. I haven't had that much need to go past 135. I move from 90 - 115 a lot but don't like the problems you can run into getting pulled over at 110+

The limit being related to the tires makes sense; I won’t try to remove the limit until I get my new rims and tires.
