I picked up a set of 12613412 injectors and would like to take a look at the stock tune.
I didnt see one in the depot.
Thanks

Looking for the same but I need gen3 tune data for them. By chance do you know the engine code?

If it's L96 then see this post by Wipped383 in another thread: Correct-IFR-tables-for-LS3-LS7-injectors-in-Gen-III~post#132

You will still need to scale the injectors... scale by sqrt(58.0/43.5) = 1.1547 (since 3 bar is 43.5 psi).
Delta kPa refers to the pressure difference between top of injector (at rail pressure) and bottom of injector (at manifold pressure)...
if FPR is 4-bar (58 psi, 400 kPa) the absolute rail pressure is 500 kPa;
MAP (manifold absolute pressure) ranges from 30 kPa (closed throttle decel) to 100 kPa (WOT);
so delta kPa ranges from 400 kPa (WOT) to 470 kPa (closed throttle decel).
