C10-Stepside

I would take it back to the main steeler for adjustment, but possibly be an accident damaged that's been previously repaired.

I have not noticed any decrease or increase or visa versa since fitting mine two months ago.

So I'm taking it you can not just put the latest firmware on, but have to add them in sequence. life was simple back in the day, if you wanted to change the rims on your car you could go straight from 12" to 15" you could, would have been a right royal pain in the butt changing an inch at at time 😉

Sorry this is my first post on here but i did notice on my iV that the firmware was lagging behind everyone on here. im still on 1803 So just how would you go about uploading the file so you can update your infotainment system, I'm a newbie to all this tech stuff , or am I better off having the main steeler do this for me.
