We started at about 80 mph he got the jump on me, but i just walked by him at about 100mph. I didn't think there would be that much of a difference between the two models. Now we have to try it from a Dig I'll keep you all posted.

With BT gearing your buddies truck is right in the middle of the low power over-rev at 100MPH since it shifts into 4th at about 105 around 5700-5800RPM, while your non BT truck is just starting to enter the lowpower over-rev since non BT will do 115-120 in 3rd. Hence the reason you pulled on him at 100MPH.
One more thing I noticed on non BT Titans is they shift at 5700RPM from 2nd to 3rd while my BT Titan painfully revs all the way to 6000RPM before shifting into 3rd. Trust me that few extra couple hundred RPM makes a huge difference.
Like I have said before in other threads if my Titan shifted at let's say 5200-5300RPM I bet it would be .5 second quicker in the 1/4 mile.
After driving my buddies '04 Titan with non BT that shifts at 5700RPM I firmly believe I would lose stock for stock. Just because of the extra over-rev.
Just my .02
