After looking at the graph again it appears the numbers on the left are not aligned, if you match them it does cross at 5250. never mind  Seems something happened from dyno room to chassis though as it does underperform.

I just received some proof pics from the track photographer which now show the launch. I see the car pics up the wheels lets them down then pics them up again (not as high) all from initial launch to just about the tree. It did this in all three sets .
Maybe I am starving for fuel ? I`d love to print the pics, but I haven`t paid for them yet.

Do you have jet extensions in the secondary

You're a bit beyond my normal realm - but in terms of basics - the PG is for lighter cars - under 2800lbs race weight is what I've always been told. So I'd think it would need mroe gear. But - before that I think the fuel system needs some work. I'd want -12 from sump to regulator and -10 from reg to carb if you're only filling through (2) inlets rather than (4). I don't know that two -8 can feed it that well considering the launch. Once the rest is worked out the convertor may be fine.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

I called Magnafuel and they said that I was NOT testing the pump correctly, to restrict the flow with the same size as the needles and seat. I hooked up one fuel line and the fuel flow doubled 
I forgot about jet extensions being mandatory on 11 second and faster cars
