The answer is NO. The engine management is going to keep the air fuel ratio the same with large injectors or stock injectors. You have to increase the air flow through the motor then the ECU will add more fuel.

What sort of power issues? If you lack the power you previously had, then the answer is almost sure either the fuel filter(s) or maybe a clogged fuel lift pump intake.

If you never had enough power and want more hp, then you need more fundamental changes. Start with air flow (which includes exhaust) per Mike Cantor's advice. Odds are your present injectors can deliver all the fuel your engine can ever use.

There are power improvement kits available for some engines. Check with websites such as Redlands RV Performance, Banks Power, Diesel Performance, Xtreme Diesel,

Banks power products. Gale Banks engineering, is the best in the business. As a ser. mgr. I always recommended them to my customers.They can get the most out of any engine, without stressing it.
