I have a friend wanting to put some LS1 injectors in a LT1.
I assume the LS1 injectors are 28 lbs. at 58 psi...
What are some constant numbers to start out and try with to get the tune close,
Im using TunerCat......

you have to do some modding to make the factory lt1 clips work with the ls1 injectors, its not too hard i just used a small saw blade and made my own slots in the injectors for the clips to fit into, a dremmel tool would work also


the ls1 injectors are rated at higher fuel pressure so your really not gaining anything unless yours are bad

99-00 LS1 injectors are 26.4# at 58 PSI.
97-98 and 01-03 are 28.8# at 58 PSI

We run 43.5.

The flow rate of a 99-00 on LT1 pressure is: 22.86 lb/hr.
97-98, 01-03 - 24.94 lb/hr - roughly what stock 94-97 LT1 injectors flow.
