Actually, gentlemen, the Gryphon does support the 4.2L. It's just that it's going to be custom only job as we don't have all the base files built specifically for the 4.2L setups. We've done quite a few 4.2L equipped trucks already and if I had more time, I'd get the cals built and included. But as you know, time is short and the work is long.
Just thought you'd like to know.

Bring back

Windows™ XP and 7.

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!
