12609749 a 54lb injector or no?

I got a free set of injectors a while back from a buddy that came out of his 2011 6.2 flex fuel silverado. Some googling pages show people say 30lb range and some 40lb range. The stock tune shows to be 54lb injector data for multiple 6.2 flex fuel trucks. Did GM use this part number for multiple vehicles with different flow rates? If they are 54lb injectors maybe they would be a better candidate for my turbo 5.3 on e85 low boost compared to my 65lb fast injectors since I keep hearing they are junk and Ill have proper data for the GM injectors.

6.2 flex fuel injectors should be 52lb/hr at 400kpa.

I'd use them, they work good and should give you a decent amount of room on pump gas. Somewhere around 500ish.
