You might have to go backwards to find that out, the
CIS injectors don't have a duty cycle.  I'd see if you
can figure it out using engine displacement and boost,
or hp levels.  The wonderful calculator at

http://www.intenzmedia.com/fahlgren/cars/turbo/glossary/turbo_calc.html

is not there anymore.  Anyone know if it has a knew
home?  I'd like to see your results, with my new
ignition system, I can really tell how important air
temps are, and my goal is to get them as low as
possible for when I want some real power in this 95
degree weather.
