Where do I find those numbers?Yes but your tuner will need to change the impedance and scaling in the PCM. You will need the part numbers for both. I believe the early LS1's were 26# injectors, later years 28#, don't know what the truck's were...but easy enough to find with the part number and a call to your local dealership.
That's a 26.3 LB high impedance injector. See what the part number is on the truck injectors. The tuner will know what to do.....These are the numbers on the injectors. 12555894, 0280155890,927,962 and 1171 on the back. Or should I repin the harness to car PCM. The intake came from a vette and my cousin has the harness and maybe PCM too. If not a I know where i can get one.
