You can definitely remove the speed limiter with a tuner, and technically speaking, it will void your warranty. BUT, as we keep rehashing lately, if you flash it back to stock before taking the vehicle in for service, the tech will not know you have a tuner, and cross your fingers, nothing bad will happen where they have to yank and examine the PCM. Mike, who posted above, is who most of us use for our tuning needs. Send him a PM and he will be more than happy to help. Welcome!
