Drive shift will be changed in the near future I just want it at 110 or 120 I don't think thats fast enough to damage anything and it will be getting speedo shut off from where it was tuned awhile back
It has 4:56 gears with detroit tru-trac not the stock grenade 80 and my silverado is customed tuned from a speed shop around in my area I just want to set it atleast 110 not the whole 120 or above
Ok my 2013 silverado already is customed tuned with hptuners software but I want to shut off the speed limiter can I do that with a hand held programmer without having to mess with the tune it has now
