Tuning larger injectors

Tuning larger injectors
I need to upgrade my fuel injectors soon, and am using LS1 edit.
Any advice on how I can update my tune to accomidate the change?
I assume the work will be done in the Injector Flow Rate Chart.
I'm changing out the stock (28#? from 2002 TA) to 38# injector.
Thanks

I have the spreadsheet and values, but I'm still a little confused.
The spreadsheet lists MAP (kPA) ranging from 0 thru 80,
but in LS1-Edit, the Fuel Injector Flow Rate table lists 100 thry 20.
So I can reverse the chart easy enough :-)
...but what about the 0 - 20 and 80 -100 values?
Do I need to modify the 'Stock Value' header range in the chart headings,
and re-scale it from 0 - 80 to 20 - 100?
Then simply slap the Final Table Vales into the LS1-edit fields? ..and thats all that needs to be updated, to accout for a fuel injector change?
Thanks!

An easier way to do it,if you have a scanner is to times the injector table by 140%.Then log the L-terms.Adjust the injector scale till you get an average around -4 to +2 L-terms.This won't take long. I've found the scales listed are pretty close but may not be perfect for every setup.

I think EDIT uses straight MAP, while HPTuners is kPa vacuum
(MAP-BARO), that being the pressure drop across the injector
along with fuel pressure. So if you are using Edit, 100=0 and
20=80 column, make sense?
