For what you have pushing a brick thru the wind thats not half Bad at all.

 

I'm going to the dyno today. I'm expecting 300/330 2nd gear pull

 

the calculator is only going to be accurate if the torque converter is LOCKED

 

Good point. I thought it seemed way to high. Maybe another good reason to buy HPtuners though.

 

what calculator did you use,link?

 

Try borrowing a GPS. That should be pretty accurate.

 

Microsoft Streets and Trips...
Thats what i use to calibrate speedometers with.
Works pretty good.
Also used it when i went 141mph
i cant remember but 3rd gear was running out of rpms fast, i think it was around 5900ish.

 

ZZebes has 4.10 gears in that vid
