I found the electronic governor on my truck the other day, at 100 mph! Holy hell are you sure this is a 6? The last vehicle I had that would dive into triple digits that easy was a V8 Buick!
It softly hit 100 then forced me back down to 90. I left my foot in it since I was late for a meeting and it went right back to 100 again The whole time the tachometer was barely reading 3000 rpm. I love this truck!

 

I felt the same way about my old 3.5!
