l59 has a different style fuel pressure regulator, and different coils also, im not sure about the sonnectors, but i think the regulator is adjusted to allow more fuel to bypass it.

Sure. You can use Edit to adjust for the bigger injectors. Then you need to change the connectors on your harness to fit the flex fuel injectors.

Send your harness up, we'll put the right connectors on it.

There's no reason you can't take advantage of the bigger injectors if you want to. Especially if you have a lot of performance mods planned for the future.

Speartech is right on... Sounds like you actually lucked out with this motor.

In HP Tuners, setting up the motor for different injectors is pretty easy.

Why doesnt someone make an adaptor connector to go between the L59 injector and the Lm7 harness?

There's no available mating connector for the injector connector on the LM7 harness. If there were, you could make a nice adapter harness.
