So I just ordered a replacement block for my jeep. Nothing too wild , but going with a 4.3 stroker kit. Was going to upgrade the injectors as I R&R the old 4.0. How long till the ecu will lean the new injectors, or I shouldn't have to worry since the factory are the same 19lb rating, just a single hole compared to a 4 hole on the new ones.
