@DRD I think that's probably what it was then because it looks like the low hp tune surging is limited to the Ultra (https://www.google.com/search?q=race...hrome&ie=UTF-8) .
I also wanted to mention that your tunes were not the issue at all as everything else with the tunes I had from you worked flawlessly.
There was something about that 60HP that the truck did not like and I believe it has something to do with the physical software of the Ultra itself.
Apologies if my initial post came across the wrong way.
EDIT: @DRD I clarified my last post to reflect the point I was trying to make since I totally dropped the ball on that.
See above! And not a problem!!
