This thread pretty much has a lot of pics and vids..You click on the pics of the truck on the track for the video..you need quick time to view.

1-2 was 6750, 2-3 was 6900... I need to do some work on the upper RPM shift points... I really have done much tunning at those RPMs, i probably need to bump up the line pressure a little bit and look at timing.. I believe I start dropping a few degrees of timing around 6700ish...
