hey guys im working on my 1987 trans am. Well more like just spending money. I took my car into a garage today and he said the injectors that I installed are at least 15% too lean for my engine.

I installed "BOSCH DESIGN III 19 LB FUEL INJECTORS". These arrived with a ford logo on them. these right here

So are these the wrong injectors for a pretty stock 305 tpi?

19lb is correct for a 305TPI with the stock ECU calibration.

Except those don't look like Bosch yellow-tops.

Need the specific part number off the injector. It will be on the side of the injector body and will be a zero followed by three sets of three digit numbers, like 0 280 XXX XXX. If it has a Ford part number on it (FXAE-XXXX) I can use that too.
