I was messing around w/ a 4.8 not too long ago. It's way easier to change the height w/ Inpa... especially since I couldn't get DIS to work on my laptop for the life of me.

All you have to do is go into the calibration and enter the amount you want to lower by. If you want to raise the car, then enter a negative value.

I also did a corner light delete for someone w/ NCS Expert. Lots of cool things you can do w/ that software
