I now know why.
I think you'll be quite happy with just the 1070. Its a significant boost from the regular idle. The only time i ever use 1300 is when i jump start, but its not like I need to. Just because I went through the hassle of a 2 way switch, just to have it. Never need it. Never use it for warming up the truck.
I'm the same as you Matt. I see no need to use the 1300 rpm to warm the truck up. The 1050 is all the truck needs.:smile5:
