I am running the predator programmer on my truck and have bumped the speed limiter to 120mph. The problem is I can only get 117mph out of the truck as indicated by gps and my speedo before the limiter kicks in:eek: . Who makes a programmer for the lly that completely removes the speedlimiter and raises the rev limiter accordingly????? I thought that superchips did, but after some reading am not so sure. Any input would be helpful. Personal experience above 120mph would be better. Thanks.

You are hitting your rev limiter. The truck will not rev any higher.
