I have an 09 2500HD. also flash scan with tunes. Problem is while driving (once while changing lanes at about 75, second while driving about 65 going straight on a two way road) stabilatrac kicks in and the truck darts back and forth like a blown tire and the traction control light comes on. the first time on the freeway I though maybe the differential was going out so I pulled the cover and checked it over, second time i was going straight on a dry road, so I pulled the fuse and it hasn't happened since. now I wan't to pull a trailer but the trailer brakes won't work with the fuse pulled out. I would hope the stabiatrac would be completely disabled in tow/haul but doubt it. does anybody have a way to disable it without disableing the trailer brakes?
I am pretty sure stabilatrac is controled thru the ABS moduel and EFI live can't reprogram that. Seems there are a lot of complaints online about stabilatrac not being able to be disabled even when holdong the button until the DIC says it is off. can I hope EFI live might tackle this or should I start looking for a new truck. Was Stabilatrac a option or is it standard equipment now
