Default Nelson tune MPG!
Got my nelson tune in a week ago.Took it on a 200 mile road trip today on interstate.I set cruise at 75 mph.I used to get 19 mpg best with my 2003 GMC ecsb with 5.3,3.73,g80.NOW today I got 21.5 MPG!It definately responds better than hypertech.I want to go to track and test before I install my Yank.

Ah such a nice thing Timing Advance is!

I'm still amazed these trucks are soooooo detuned in stock form. You not only get power but economy at the same time. Amazing!
