LS7 E38 using ACDelco 54 lbs Flex 12609749 injectors data transfer help

[Racerbox77]

I'm building a C6Z06 LS7 HCI and I'm hoping it will make 625+ whp. That power will put the OE 42 lbs injectors over the limit. So I started researching injectors. I was going to go with Injector Dynamics because I've had good luck with them in the past and they have good injector data available. But instead I took advice from a few that have used Flex fuel Delco injectors with great success. They told me the inj. data is great and the cost is as well.
So I bought AC Delco flex fuel injectors that come in 2009-2013 Escalades and Silverado's. The part # is 12609749 and flow about 54 lbs from what I've read at 58 psi.
I've realized now the injector data is not as simple as Injector Dynamics makes it.
I found a tune from an 09 Denali on this forum which has the correct inj data but the values in the tables don't line up. So when it comes to converting the Offset Vs. Pressure Vs. Ign I'm not sure how to accomplish this.
Any help is appreciated.



Thanks
