Try to get a little momentum on the downhills if you can, the uphills will bring your speed down to 45-50mph most likely. If you can get the turbo spooled up prior to starting a climb, it will be easier to keep the boost up while pulling the hill. Have fun, you're going to see what these trucks are made for!

I'm going to get a reburn and add 80 tow to see what it does. It definitely will feel better 65 and up than it will at 55-60, so don't hesitate to try out a few different speeds to see what feels best with your setup.

Good luck and be safe
