Gen IV LS Swap E38 ECM P2122 and P2138 DTC - limp mode

All of the injector needs to be right, not just the flow rate. But I would be surprised if you can get any real data for them. Advertised flow rate probably isn?t right either. I just don?t expect investors that cost less than $10 each to be worth anything.

We are going to switch them out with GM 50lb/hr injectors but the truck not responding to throttle and trying to die when you press the pedal could be because of the variance in the injectors and what?s tuned right?

It definitely will not run correctly with bad injector data and no attempt to tune around the injector data.
