Re: stock to 42lbs need % for ls1edit Here's how I did it. I'm not sure if it's the best way but it got me really close...
I figured out what my replacement injectors flowed at a certain PSI (or kPa) and then figured out what the stockers flowed at the same PSI (or kPa). Then I divided the two and multiplied the numbers in the stock table by the result. For example, in your case if you've got a '98 (stock with 28 lb/hr injectors), you'd divide 42/28 and get 1.50. Now just multiply the numbers in the injector flow rating table by 1.5.
Like I said, I don't know if that's the best way but it worked for me.

Re: stock to 42lbs need % for ls1edit The edit whole table should work, Remember it is in percent, so to mutiply the whole table by 1.5, You would enter 150, for 150%, then hit the multiply button.

I agree 100%. That's what I do, except you may have to play with it a bit to see if you want to keep that sloped curve or flatten it out. Some cars ran better with the Injector offset curve as a straight line.
That's why each is different and there are no absolutes.
