question about changine fuel injectors

[Ethan_Bill_Bennett]

I just installed a 7.0L in my 02 trans am with 11:1 compression and 42 lb
LS3 injectors. I am currently running the stock fuel pump (which I plan to change to a 255 lph soon) so I am pretty sure the rail is regulated at 4 bar.

In the "injector flow rate vs. kpa" table I am just going to scale the entire row by a number to bring the flow rate at 0 kPa up to 42. In my case it happens to be 1.24. I am going to post the tune for anyone that is interested.

My question is, is this the proper way to tell the PCM what size the new injectors are?

There are spreadsheets on the site that give you the information about specific injectors. The LS3 injectors are a pretty common topic on here and the excel worksheet can be found in a number of places.

No problem. I know it can be a pain sometimes to get information from this site.
