They don't "flash" your truck to recalibrate the speedometer. Flashing refers to updating software. To recalibrate or turn on high idle is much simpler. When a truck is flashed it willget all past and presentsoftware updates. There are features that can be enabled or disabled. Can't remember them all. But high idle, Daytime running lights, rolling locks, automatic unlock, horn beep/ light flash when doors lock/unlock, headlight delay time are a few that I remember. I do these for free for my customers or for forum members. This process does take a few minutes, but to charge more that 1/2 hour for labor is too much in my opinion. But then I can use the STAR Scan and not have to pay/get a tech to do it.
