Hello,

Can anyone answer some questions about TBI injectors. I bought an engine from an junk yard and the injectors on it are labeled:

5235209 on both,

then one of them has 0135 on it and the other has 0145 on it.

1) I was wondering how I could figure out the flow rate of my 4.3 injectors?

2) Why do they have two different injectors on it?

3) If tuning, do I need to be able to enter two different flow rates into software?
