Glad to hear it.
As to the flutter, can you offer a bit more detail? Is this meaning something like a rough idle? Odd noise? As for the idle, it's not uncommon to get a little hang with a performance program. It's related to changes in the Injection Pressure table which are used to help improve throttle response. Some trucks will experience it and some won't. It mostly just depends on how efficient your HPOP is.
Let me know on the flutter and I'll see what we can come up with.
Take care.

Windows™ Vista and

Windows™ 8 is a pain in my a$$!

Windows™ 10 is only slightly less annoying!

Windows™ 11 is garbage!
Much to my surprise, I'm actually quite enjoying Linux!
