Alright guys, here is what I got from my logs:
I did about 3 runs in each gear on the same stretch of road and looked at the logs.

At redline in 1st gear I was pulling the follwing Gs at redline:


At the same speed of at redline, I went WOT in second gear and pulled the following:


The Gs before redline in 1st gear is higher than the Gs at redline, so if I were to shift before redline, I would be loosing acceleration.

Let's look at the results from the redline area of 2nd.
At redline in 2nd gear I a was pulling the follwing Gs at redline:


At the same speed of redline (2nd gear), I went WOT in third gear and pulled the following:


Notice that the acceleration in 3rd gear is greater than redline at 2nd, so I went down the curve and found the speed of where the acceleration on the end of 2nd gear matched the acceleration of the speed in the next gear.
The speed which I should shift is approximately 67 MPH.
67 mph with my setup is approximately 6750 ish RPM.
