: Injector Size for a 6.2L?

Anyone know the factory injector size for a 2009 Escalade - 6.2L. Any benefit to upgrading them? Thanks.

Not sure of lb/hr. rating, but the injectors were changed for the 2009 flex-fuel-capable version due to the 2007-8 versions being almost static at WOT. In other words, near the power peak at full throttle they are essentially locked open. Since E85 has only about 70% of the energy content of regular E10, the flow rate must be increased to yield the same power output..so the 2009 injectors flow more than 2007-8 injectors.

I would think that if you moved up to the bigger injectors... the ECU would need an update as well.

I was thinking of putting a tune on it, but deciding whether to buy bigger injectors. No one has the lb./hr. number?
