injector constant changing?
A friend and I are curious as to simply changing the injector constant from 22# to 32#(car now needs it) does the programming do anything (perhaps behind the seen)to pulse widths/duration or am I tagging it to say 32# for my reference in
the future for whatever reason?

As long as you HAVE injectors that deliver "roughly" 32# then the ECM properly compensates and all should be fine. You may have to do some "tweaking" for VE Tables, Acceleration/Pump Shot Tables, IAC/Idle, Deceleration/Fuel Cut-off, but that is normal. Heck, I found myself having to tweak all those and my engine is basically stock.

Did you keep a record of the stuff you changed as you changed it? I'd be curious to see someone's "journal" of their PROM experience if anyone has one.
