I'm not positive either way wether using a presumably larger injector (as in the 4.3L) is going to be positiv negative or no effect on your engine buildup. The way I understand it is the computer dictates your fuel metering during closed loop operation via your MAP, coolant, 02, tps and rpm measuring. If you use a larger injector aren't you going to force the engine to run the injectors at a very low flowrate to adequately fuel the engine? Don't forget your engine mods won't require more fuel than a bone stock 2.8.
