Default 121 MPH

Ok, I was on my way to Vegas...again and instead of trying to get the ultimate gas mileage, I decided to open her up and see what the all out speed on level pavement was. With the SuperChips programer in performance Mode and speed limiter off and rev limiter raised I hit 121 MPH.....granted it took some time over 110 MPH but that's where she topped out.

Wait, From my experience, in my 06, the gear throws are roughly (when pushed to red line)
1st - 40
2nd - 75
3rd - tops at 100 with gay-vernor at only like 4k RPM

So... I was expecting faster?

Wow, I'm amazed the fuel pump could keep up at that speed!

They do unless you have a tuned PCM.
