Use tow/haul mode and use the manual shift buttons to raise rpm above 2500.Is there anyway to engage or disengage the exhaust brake on the GDE Hot tune
I don't have the tune myself, but with tow/haul mode on, the trans does shift down sooner if you lightly apply the brakes and that helps with the brakingThanks I just installed the tune and could not detect any difference . And there isn’t much information on the Ged web site
