Default 2007 5.3 Silverado speed limiter
I raised the speed limiter setting in the Speedometer section of EFI live in both the fields (one for regular and one for drive by wire) but the truck is still cutting out at 98mph.

Is there another setting somewhere for the drive by wire trucks I'm missing?

What's your RPM/gear when it cuts off....., could be cutting fuel also unless you raised the RPM limiter...

No such thing as a stupid question... it's an easy one to overlook.
