I can only see a 2-400 rpm drop between gears depending on what gear it goes to. I'm uploading a video now of one of the runs at the starting line

Changed to a PTC 32-3500 converter for turbo. Truck is now on 11psi about, 183 kpa. Taking it back to the track to see how my results turnout. This nc heat and humity is not helping me any.

Truck feels alot better with a tighter converter on the street. Best pass for the night was 12.20 at 113 mph with a 1.90 60ft. This new converter is so much tighter that I will have to build boost to get it out any faster. Getting some flare up on the 2-3 shift, and let completely out, then got back in it. Pretty happy with it so far, just need to get my 60ft back down where it was with the old converter or better. With a 1.6 range 60ft like it has gone before, easy 11s.

The mph is a nice step in the right direction. Now to dial in the launch power...

Try getting timing a tad more aggressive in those lower boost and g/cyl regions you first come off the line at and see if there are improvements to be had there. The next obvious answer is building a little boost off the line.
