I have a 2003 silverado with an ls1/6 setup. I have been using the stock 03 truck intake with 25# injector, but I am now out of injector (102%DC over 5000rpms).
I purchased a newer style truck intake with the larger TB, larger ls2 injectors (GM # 12569113), and return-less fuel rail.
If the injector data for these injectors on a return style fuel system already exists, I would prefer to modify the new return-less style rail into a return style.
So far all of the tunes in repository I have found, show the FLOW RATE VS KPA as incrementing. This means its a return-less style fuel system.
I need to find a vehicle that has these ls2 injectors (GM # 12569113) and a return style fuel system, so I can find the correct injector data.
Anyone know?
Thanks
