millergt Posted August 11, 2006 Posted August 11, 2006 I've got a 2005 LS 430 and would like to reprogram the computer to take off the speed limiter and maybe free up a little more horsepower. I've done this with many other cars but don't know where to look for companies dealing with hand held programmers for this car. Any help would be great. Thanks, Rick
