Get my car to launch better...

I lowered my 60' on my Duster from 2.4 to 1.81 by doing this stuff in order:

Went from skinny rock hard street tires to M/T ET streets 275/60/15's lowered sixty foot to 2.2 (still bad)

Chucked the MP crap converter and installed PTC 9.5" 3,500 stall lowered sixty foot to 1.9 (getting better) btw, adding the PTC converter was the best improvement I've ever done for the car.

Pulled the ESPO HD springs (stuck them on my Dart so no waste) and installed SS springs that I got for $50. Sixty foot didn't change BECAUSE the shocks weren't long enough.

Added '80 something Dodge D250 truck shocks and got my best 1.81 sixty foot, and best ET 12.91 @103.7.

Great post guys, I love stuff like this.
